Michael Atkinson, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.12 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Summary changed: - Ubuntu Slow, crash, sluggish from version 10.04 upwards on i3/i5/i7 machines + Ubuntu Slow, crash, sluggish from version 10.04 upwards ** Description changed: - This is an attempt to get proper attention to the massive amounts of - people stuggling with ubuntu freezing at random, or becoming very slow - or sluggish. ( https://bugs.launchpad.net/ubuntu/+source/xserver-xorg- - video-intel/+bug/993187 ) - - Developers won't work on it because the problem is not given enough - detail. This is however a severe issue. Here's my info gathered so far: - Ubuntu will at random points suddenly become very slow and sluggish. graphics run far behind, keyboard strokes take multiple seconds to show, graphics are updated in super slowmo mode, or if you're unlucky; the system dies completely. This is related to a problem with the interrupt handling. On my own machine (MSI i7, nvidia card, 16 Gb, 5 sata HDD's) I have had this problem from 10.04 (when I bough the hware) up to 12.04. I have since upgraded up to various kernels up to 3.5.3 with varying results. Some of the suggestions in posts make the periods between crashes shorter, some days it works fine, some days it happens every five minutes, but it NEVER goes away. If you consider this is interrupt related, that makes perfect sense. Every single 'crash' is marked by an unanswered interrupt. See below syslog: Sep 5 15:13:14 Server kernel: [112195.631364] irq 16: nobody cared (try booting with the "irqpoll" option) Sep 5 15:13:14 Server kernel: [112195.631368] Pid: 17901, comm: firefox Tainted: P O 3.5.3-030503-generic #201208252335 Sep 5 15:13:14 Server kernel: [112195.631369] Call Trace: Sep 5 15:13:14 Server kernel: [112195.631370] <IRQ> [<ffffffff810e5a5d>] __report_bad_irq+0x3d/0xe0 Sep 5 15:13:14 Server kernel: [112195.631378] [<ffffffff810e5ce5>] note_interrupt+0x135/0x190 Sep 5 15:13:14 Server kernel: [112195.631380] [<ffffffff810e3559>] handle_irq_event_percpu+0xa9/0x210 Sep 5 15:13:14 Server kernel: [112195.631382] [<ffffffff810e370e>] handle_irq_event+0x4e/0x80 Sep 5 15:13:14 Server kernel: [112195.631384] [<ffffffff810e6874>] handle_fasteoi_irq+0x64/0x120 Sep 5 15:13:14 Server kernel: [112195.631388] [<ffffffff81016632>] handle_irq+0x22/0x40 Sep 5 15:13:14 Server kernel: [112195.631391] [<ffffffff816a49ea>] do_IRQ+0x5a/0xe0 Sep 5 15:13:14 Server kernel: [112195.631394] [<ffffffff8169a86a>] common_interrupt+0x6a/0x6a Sep 5 15:13:14 Server kernel: [112195.631395] <EOI> [<ffffffff816a2c2d>] ? system_call_fastpath+0x1a/0x1f Sep 5 15:13:14 Server kernel: [112195.631398] handlers: Sep 5 15:13:14 Server kernel: [112195.631401] [<ffffffff814bc670>] usb_hcd_irq Sep 5 15:13:14 Server kernel: [112195.631462] [<ffffffffa0d65cb0>] nv_kern_isr [nvidia] Sep 5 15:13:14 Server kernel: [112195.631470] [<ffffffffa00640f0>] rhine_interrupt [via_rhine] Sep 5 15:13:14 Server kernel: [112195.631471] Disabling IRQ #16 The problem is massively compounded by the fact that irqpoll and irqfixup options NO LONGER WORK AT ALL ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/855199 ). No matter if you switch to Nouveau, diff kernel, or other drivers, the problem remains is varying severity. Again; logical if there is a problem with the kernel interrupt handling itself. So here's the kicker. It is easy to resolve! By forcing a restart of the interrupt handlers the system INSTANTLY comes back to 100% functional life: root@Server:~# service network-manager restart My theory (for what it's worth; I have programmed assembly for 30 years) is that there is a multi-threading fault somewhere, which causes the kernel to miss an interrupt, or to miss allocating it. - There is truly no point in uploading hardware specs and/or software - config to this bug. There are litteraly thousands of different configs - experiencing the same issue. The one thing they have in common though: - Shared interrupts (usually 16) and LOAD on that interrupt (USB (KB+MS), - VGA, ETH) on high speed machines. - - I strongly urge the kernel people to accept responsibility for this one. - The problem is getting very much out of hand because it seems to get - worse as CPU power increases. And more and more people are increasing to - I7 etc.... Hence the massive flood of problems. + The one thing they have in common though: Shared interrupts (usually 16) + and LOAD on that interrupt (USB (KB+MS), VGA, ETH) on high speed + machines. I have created a keyboard shortcut that does the service restart and this works perfectly 100% of the time. If any dev needs more info, contact me. - I hope this gets some very VERY high level attentions VERY soon. This is - extremely damaging to Linux in general. - Just to prove a point: Same machine on win7 works perfectly.
