It seems as my "stuck on TLB IPI wait [CPU#1]" problems disappeared
when I changed from OSS to ALSA.
After upgrading the system to Debian potato (X and Gnome are the
latest from unstable) and installing the kernel 2.2.16 (Debian call it
2.2.17) from source I got a lot of problem with spontaneous crashing
and also the message "kernel: stuck on TLB IPI wait [CPU#1]" now and
then, when the machine was not responding for some seconds.
To confirm that it was a problem with my system I installed an identical
system on another machine (almost same, one is using ASUS P2BS and the
other one uses ASUS P2LS, both with 512 Mb ECC and scsi-disks), I got
the same problem on that machine.
I then upgraded one machine to 2.4.0-test5 when I got rid of
the "kernel: stuck on TLB IPI wait [CPU#1]"-message, but...
I still had problems with spontaneous crashing.
I then found that after the upgrade my default compiler was
gcc 2.95.2, which, according to the linux smp documents is not
trusty on the kernel. I then recompiled both kernels with gcc 2.7.2.3
and after that it worked much better, not so many spontaneous crashes.
I still got the "stuck on TLB IPI wait" although. I then tried to change
from OSS to ALSA (ALSA with SB Live is just wonderful...) on both
machines and then got rid of the "stuck on TLB IPI wait" completely
and much more stable systems.
I still get some rare sporadic crash, especially after some mouse events,
but it's very hard to say what is happening, if it is the kernel,
X, Gnome or what...
Any hints of how/what to log to catch such events as the machine
has to be rebooted, it is not responding to anything as keyboard,
mouse or ethernet ?
