description |
Since upgrading to Maverick, I'm frequently observing instances of the timer interrupts suddenly stopping being processed (or even produced?) for a few minutes. The system becomes sluggish as a whole, all CPU cores go high on Sys% usage. This continues for 3-5 minutes, then suddenly goes back to normal, just like how it started.
It is certainly related to the timer interrupt: If I continuously 'cat /proc/interrupts' (or just run it under 'watch') during the time the system is affected, interrupt 0 (IR-IO-APIC-edge timer) stays frozen until the problem goes away. No messages appear on dmesg or in /var/log/kern.log.
The problem always starts at random, with no particular cause, but it seems more frequent when making heavy use of both sound and graphics at the same time. It is very common to happen when I start playing some game on Wine. It seems to also vanish at random after 3-5 minutes have passed, but zapping the X server seems to a way to restore the normal behaviour (it happened twice until now, I need more tests to confirm).
I don't know what more I can say about this issue, but feel free to ask; I'm willing to provide as much information as possible to have this fixed.
