Hi,

Since yesterday, some processes are really slow on my Lenny/Sid.


I found this in /var/log/messages:
[1510354.692239] Clocksource tsc unstable (delta = 51799116882 ns)

KDE clock is 10 hours late, bash is really really slow, keyboard repetition seems broken or really long to start, etc.

I generally see messages like that; I always assumed they were harmless: Sep 23 00:13:54 lizzie kernel: Clocksource tsc unstable (delta = -85149529 ns)

Thank you for your answer.
Today, this message is not harmless: many things are so slow...


Strangely Icedove & Firefox are ok, so I can read/write e-mails...

Apache/PHP/mySQL are a little slow too.


Any idea ?

As I don't want to reboot my Debian (so bad to do that !), I'm waiting for possible fixes from the list and Google too. In general functionalities that require a specific timing are really slow, even the bash/Konsole completion beep that spends about 10 seconds !

I doubt the "Clocksource tsc unstable"-error causes the slowness, as that is a common error on some of my machines too. Apparently something is hogging your system. Can you give us the result of top?

Since my last mail, I rebooted the machine (using reset, init 6 wasn't able to reboot after a few minutes). Just before reseting, top was long to start displaying stats and then it started to work nice (normal speed) and showed 9999% CPU usage on certain processes !

It was not often the case, some stats snaps looked good.

Well, that at least explains why the machine was/is slow. Killing these processes might help.

Then, I had troubles when I logged into KDE: it first failed (kind of freeze while waiting for something that never comes), I restarted X (ctrl+alt+backspace) and then KDE login was ok. In KDE, I now see that the audio hardware is no more recognized (according to kmix & amarok/xine (failed to start xine engine)), but snd* modules seems to be loaded as appropriate...

Strange, although a /etc/init.d/alsa-utils restart sometimes works, or realoding the sound modules. Then, you probably also have to restart kdm

I wonder about a hardware failure...

This Debian was installed a month ago and I didn't any problem before, even on the Fedora I had before for a year on this hardware.

That can of course be. Try running memcheck, and try booting from a live-cd might give you some clues.

/var/log/messages also reports some ACPI errors & warnings (but I don't really understand them):

Sorry, I'm centrainly not an acpi-expert. Let's keep the discussion on the list, maybe someone else can help.

# grep -i acpi /var/log/messages

Thanks for help, I don't understand yet what kind of problems I have...
