X (3.3.x), SMP, and 2.3.40 don't play nicely together

I have an ABIT BP6 SMP motherboard (the one with all the problems,
see linux-abit@geek.net for more info), running linux (debian unstable).
I have a matrox g400 max 32mb running at 1600 x 1200 x 32 x 85Hz.

I recently upgraded to XFree86 3.3.6 in the debian 3.3.6-3 package, while
running the 2.3.39 kernel. All was good.

Then, I upgraded to 2.3.40. Immediately afterward, the X server began
locking up after ~30-120 minutes of use, consistently. I tried using
the 3.3.6-2 and -3 debian packages, the 3.3.5 and 3.3.6 binaries off of
xfree86.org, with the same results. I could ssh in from my laptop, then
sometimes I could kill the X server; other times it was impossible to kill,
and I had to reboot, and other times it took 5 minutes to die.

This happened with the glx module for g400 enabled as well as disabled,
so that is not the problem.

I downgraded to kernel 2.3.39 and all was again good.

I didn't change any kernel settings between 2.3.39 and 2.3.40 compiles, AFAIK.
.config, bootup messages, etc. are included as mime attachments.

I'm pretty sure this is a kernel/x/smp thing, not a bp6 hardware thing,
but not totally sure. There have certainly been a lot of problems with bp6
hardware, and X is implicated in many of the crashes.

18:46@tiger:~# uname -a
Linux tiger 2.3.39 #12 SMP Tue Jan 11 14:27:48 PST 2000 i686 unknown
19:08@tiger:~#

I guess I should go back to 2.3.40 and strace the xserver sometime.

Thanks,
Ryan
