Hm, updated my machines to 2.6.20 and 2.3.0 rev 2222. I still see ( less
frequent?) some backtraces occuring on my console, either during reboot
or sometimes when running the testprogram and reloading the modules.(see
dmesg snippet below) The Celeron M still crashes often totally.
My main-application still freezes the SMP mashines if I have 'priority
coupling' enabled in kernel-config. Using trunk makes things even worse.
The pc will crash during startup of my app, the testapp I sendt you
works, but i can not shutdown the pc afterwards, because it freezes
completely when terminating kdm.

dmesg tells me the following (2.3.0.2222, 2.6.20, SMP):
Latest I-pipe version?
Kernel was freshly patched with:
./ksrc/arch/i386/patches/adeos-ipipe-2.6.20-i386-1.7-02.patch
the one from svn rev. 2222

Trying to fix it up, but a reboot is needed
Something is corrupting kernel memory.
I did some remark on your test, let's get back to it: You are running
the test at 100 kHz. That /may/ have side-effects like overload, or it
might actually trigger some stack overrun. Did you enable the stack
checks? Can you confirm the problem occurs also at slower tick rates?
Test was run at 10KHz, but stack-debugging wasn't on, I will repeat it
and post again...
