What were you doing with the device before it resets ? If it was mounted and it somehow reset, it could be even a flaky cable. Check, also, that hald-addon-storage is probably polling an unexistent /dev/sdX.

Don't have hw to test and the problem is not on the reset I suppose. The reset happens probably because the device disconnects before. I suppose it's some sort of current spikes during copy operation. Might be some "quirk" in AMD ehci only. Dave, any comments ?

What makes you think that nothing gets recognized by ehci-hcd? Did you try unplugging the device and plugging it back in? Or did you try plugging in another high-speed device?

My previous setup was: * Direct attached to PC: - Disk - Keyboard - Hub * Attached to HUB: - Dock for digital camera (off) - Corded mouse - iPod In my previous setup the USB system would die when doing lots of disk access on the USB disk. New setup is: * Direct attached to PC: - Disk - Keyboard - Mouse The system has been up and stable for hours wiht lots of very heavy activity on the disk. The hub is currently plugged in to another machine (Win2k) and is working just fine. Any ideas on what information I can provide?

Badly slow access and dozens of damaged DVD+RWs (grrr...) are the most serious symptoms of this problem. Resets appear in bunches of about 20 - 100 in the kernel log. There are no other error messages between two resets. (I did not switch any special debugging options on...) Resets occur approximately every 30 seconds. Some bunches of resets are followed by a fatal series of I/O errors and rewritable media destruction. In many cases, however, normal operation is resumed after minutes of resetting and waiting. (Which does not save the DVD+RW from destruction, as unexpected delays seem to be a problem, too.) I saw some interesting backtarces complaining about bugs in the pktcdvd module. Unfortunately, they occured on a kernel tainted by tha madwifi ath_pci module. So I don't know whether I should post them here or not. Will try the autosuspend experiment mentioned here [https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.20/+bug/88746], but I don't believe this could work. Autosuspend is disabled im my kernel config. Enabling it and then re- disabling it at run-time does not sound logical to me. But I would do just anything to get rid of this awful problem.

Wanted to add some additional info that I forgot to mention, although it's probably not technical enough to help debug anything: when I boot the Linux systems and hit escape to clear the OpenSuSE splash screen and look at the boot messages there's garbage amongst the messages, eg: ^[^[^[^[^[^[^[^[^[^[^[ Your boot message here... When I hit a backspace the garbage stops. Also, I recently added a fourth system to the KVM that has a GeForce 8200 chipset. With this system when I boot and go into the BIOS, quite often the BIOS starts flashing screens/popups rapidly as if it's receiving keyboard input. Sometimes by hitting backspace I can get it to stop, sometimes I can't. Once the system boots it's fine and it also is fine with external USB drives. I've posted a support request with ATEN. Hopefully, I'll get back to testing it some more this week or next.

And they would explain the disk problems: Many EHCI controllers have a bug which causes them to temporarily drop data on one port when a device on a different port disconnects. I'd say that whatever is causing the keyboard communications to drop out manages, every so often, to interfere with the disk traffic. The computer then tries to reset the disk drive, but many USB drives have a bug which prevents them from resetting correctly when they're in the middle of an I/O operation. As a result, the drive becomes unusable and the system puts it offline. As for what causes the keyboard problems... I don't know. It could simply be a cabling issue. For example, I've got a USB-to-PS/2 keyboard+mouse converter. It doesn't work at all when plugged directly into my computer, but it works just fine when connected through a USB extension cable. Try and figure that one out! You could try using a different keyboard. Maybe it wouldn't get all those communications dropouts when plugged into the DLink hub or the ATEN switch.

I understand this is not your vanilla kernel, and it's not involving the same type of devices as reported initially here. However please bear with me and read on. First I'd like to bring your attention to the fact there has been many similar bug reports about usb resets on various distro, a few examples are: https://bugs.launchpad.net/bugs/124406 : the resets affects keyboard and mouse https://bugs.launchpad.net/bugs/91230 : idem, just older http://www.mail-archive.com/linux-usb-users@lists.sourceforge.net/msg18199.html http://taint.org/2006/12/13/191554a.html http://bugs.gentoo.org/177266 https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/54419 ... There's plenty more if you search the net with these keywords: reset speed USB device using ehci_hcd. I believe it's a long standing bug which is elusive and difficult to track. What I observe across a lot of reports is often the following: - It gets dismissed by being hardware related. Certainly some of these reports are due to bad hardware. However there are many cases where the same config works perfectly well with other non-linux OS. - It's often resolved by trying to connect the affected devices differently. In my case it seems I had to put my external keyboard and mouse to a separate hub. - Many people are getting frustrated with it and either give up or play around like me. I gave up on migrating to linux a couple years ago because of this bug. Being so elusive and widespread, many of these bug reports end up with either no fix, or a workaround like mentioned before that does not really address the issue. And since nobody can do much about it, these reports become inactive/closed. One of the most active thread on this bug (first link I gave above) is probably going to end up being closed because it has been judged too "messy" (I agree but that's no reason to close it, it's just a messy bug). One might argue there are more than one bug here, because different devices are affected. My guess however is that it's one bug affecting various devices (hd, kb, mice, ...). In fact, having played around a bit, I would advance the theory that it is related to the presence of devices with different speed on the same bus/hub (lo+hi and lo+full for sure, hi+lo most likely). If you look at this post, you'll see a report of this bug on a usb 1.1 machine: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/124406/comments/254 So it could be (pure speculation) that this bug has been introduced since the addition of ehci, and is affecting usb1.1 as a result of the changes made to accomodate ehci. According to http://www.mjmwired.net/kernel/Documentation/usb/ehci.txt : Note that USB 2.0 support involves more than just EHCI. It requires other changes to the Linux-USB core APIs, including the hub driver, but those changes haven't needed to really change the basic "usbcore" APIs exposed to USB device drivers. Anyway, my point really is this: this bug is probably more widespread than one can imagine, it affects many distro, it's been reported many times over in many places with different facets. This bug report #11159 is probably the only open and recent report of this bug on the kernel list. So please, don't dismiss it because it's too elusive or leads to a messy discussion thread! I consider this bug to a linux killer, and there is a real need for the kernel team to be involved.

Who has verified that the fix committed earlier has resolved this issue? It's not because the last person talking here said it was hardware-related that there was no bug. Ideally we should find a machine/configuration where this bug has happened, test without the fix, test with the fix, and then conclude. Please read my comment #67 above. This bug has been occuring regularly and people report it mostly against distros bug tracking. Since distro can't do much they often close the report because they find it hard to track and do anything about it. This practice of closing bug because they're too elusive to track isn't right, even less in open source (what's the problem with how long a bug is open?)

If you do have this problem, with the 2.6.30 or later kernel, please post to the linux-...@vger.kernel.org mailing list the kernel log messages and we will be glad to work with you there.

The bug report was opened more than a year ago. How can you call that "quick"? Evidently you did not receive the message I sent to you in response to comment #67. The gist of it was that this is not a single bug. Most of the bug reports you cited were either non-reproducible or caused by hardware problems. In others the reporters have stopped responding, making it impossible to find out what was wrong. So far there has been extremely little indication that errors in the software are responsible for these resets. Even if it is true that the software is partly to blame, we have no way to fix it unless we can find out exactly where the errors are. Errors get fixed when they are tracked down, and your rant doesn't contribute towards tracking down any of these problems.

I did receive it, but I was just starting out with linux and couldn't really deal with kernel hacking, I needed to get going with my work. > Most of the bug reports you cited were either non-reproducible or caused by > hardware problems. > In others the reporters have stopped responding, making it impossible to find > out what was wrong. That's what I call hard to track and elusive. Does that mean there's no bug? No. If there's a bug, even if hard to track, I think there should be an entry for it. All this talk about keeping a log only for reproducible bugs does not make sense to me, and only reflect a dislike for unreproducible bug. > So far there has been extremely little indication that errors in the software > are responsible for these resets.

That's what happened for the last two years: it gets reported and then closed, it reappers somewhere else but the OP quickly disappears because this bug is a showstopper (you can't work with it). Anyway, there's no need to consider this a rant and get personal about it. I appreciate a lot all the efforts from the so many people in getting GNU/Linux to where it is now. Also, bear in mind that in the past 4 years I really wanted to get away from M$. This bug kept me from making the move. Only recently did I try again, got this bug again, but did not want to get discouraged because of it. So I'm sorry for making so much noise, I'm tired of this bug as much as you are, but I don't want to forget about it. Is the fix you talked about in 2.6.30? If so then it should be in my arch release kernel. I'll rewire my devices (in order to reproduce the bug) and report back in about a week when I have more time to play.

If a bug isn't reproducible and can't be tracked then there is no hope of fixing it. In such cases, whether the bug report remains open or not doesn't really matter much. > How do you explain other OS had no issue in the same configuration? I can't explain it because I haven't been able to obtain enough information. Mostly this is because the reporters stop responding, but occasionally it's because special debugging hardware is needed and the reporter doesn't have it. One possible explanation might be that the drivers for the other OS were written with special knowledge of some bugs in the hardware. Manufacturers often don't share such knowledge with open-source programmers. But I have no way to know if this is the case here. > Closing this bug doesn't contribute in nailing it down.

You are making a very common mistake: confusing the bug with the bug report. I keep telling you that what we see reported here, in this one report, is really many different bugs. Several of them have already been tracked down and solved. You don't seem to understand this. > Only recently did I > try again, got this bug again, but did not want to get discouraged because of > it. So I'm sorry for making so much noise, I'm tired of this bug as much as > you > are, but I don't want to forget about it. If you would like to contribute, please open a new bug report. This is because your problem is almost certainly caused by a different bug from the one that originally led to this report. > Is the fix you talked about in 2.6.30? Only partially. The most recent code is available in 2.26.31-rc5 together with this patch: <http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/gregkh- all-2.6.31-rc5.patch>.

I'd be happy to use whatever debug kernel that will work on my arch system if one cares to provide it. I'll open a new bug report if needed and back link to this one because even if there are other bugs that got mingled, I find that most of the discussion here relates to the resets I experience with my keyboard and mouse.

Earlier in the thread keyboard and mouse were mentioned as well as resets so I thought it was a good place here. Initially I reported my issue against ubuntu bug 124406 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/124406?comments=all). However this bug got closed because it was judged too messy. I felt this bug did not get the proper attention it deserved, so I came here because I thought the kernel team would be more able to deal with it. I entered comment #67 and also created another ubuntu bug entry (see https://bugs.launchpad.net/ubuntu/+bug/383722). There you'll find more info on what I experience along with relevant dmesg logs. I understand your point except that in practice when a bug is difficult to track and reproduce it gets reported in many different ways, and there's not much we can do about that. I'm sorry to be so forthcoming but I'm tired of always seeing this bug getting dismissed in similar ways: can't reproduce, OP gone, confusion with other bugs... If we keep sticking to the rules of clean and reproducible bugs then we'll never become good at dealing with concurrency issues and parallel computing! BTW: I can reproduce the bug and so does Rolf Leggewie (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/124406/comments/254).
