Kalidarn: the "timer" interrupt must ALWAYS increment. It is produced
continuously by the hardware, hundreds or thousands of them per second.
watch keeps running that command every 2 seconds, so, the number is
always changing. The kernel uses this interrupt mainly for process
scheduling. If for som
I'll throw in that it is still happening for me. Before, I was probably
"lucky" enough to hit the gaps, both in observation and usage. Same symptoms,
with or without VMs running, all CFQ scheduling. Not sure if HDD layout/config
affects this, but maybe it'll help isolate the problem:

I did run "watch -d grep timer /proc/interrupts" and I'm not sure if it
was my imagination but during the laggy period the numbers didn't seem
to change as often. What exactly am I looking for?

Oh and I have a NVIDIA 470 GTX. I considered using non-proprietary
drivers such as nouveau but the current version in the repository
doesn't support the Fermi series of cards.

Yes my machine also has an i7 930 in it. I have not yet checked the

Kalidarn, please help us delimit the problem. From your linked thread, I
see you have nVidia, it is a match with the problem related here. What
is your CPU? Is it by any chance a Core i7? Do you see the timer

I have this problem with my system, initially I thought it might have
been KDE as I was using Gnome in 10.04. I later found that the same
thing occurred when using fluxbox so it obviously wasn't KDE related.

Since updating to mainline kernel 2.6.37-rc1, I'm also not experiencing
the issue. But I also found and removed a faulty memory module from my
system.

Unusually enough, the issue seems to have resolved itself on my end. I
haven't experienced any hangups for the past few days; checking on the

I'm seeing similar behavior on a Server install of 10.04.

It happens without any apparent cause to me too, even with the system is
idle.
It just appears that under normal operation, it happens 2-4 times a day
(completely random, no fixed interval between events); but if I start
playing Portal, for example, it happens in less than 30 mins (again, at

Same CPU/video card, although for me the timing is closer to 1-2 minutes
of lockup. Unlike the original report, though, this seems to happen
without _any_ apparent cause - even if the system is completely idle,
there will be occasi
