Subject: The never ending BEEEEP/__smp_call_function_mask with 2.6.25-rc7

Hi,

Ever since I went to the new 2.6.25-rcX, I encountered lots of random
system freezes after about 2 or 3 hours of uptime... but until now, 
I couldn't _catch_ them, since the system
(AMD Athlon 4200+ X2 (Manchester) / nforce 4 SLI / x86_64) went
straight into oblivion (nothing on the serial console or anywhere else,
heck I couldn't even hit reset, It didn't POST anymore)

So. take a look at stuck_task... that's best backtrace I could get...
(I have other logs too. (Task-list / Lockdep / ... ) but it's too much
and I hope the _logs_ are already enough.

BTW: I noticed that the clock seems to jump forward and backwards.
Is this because the CPU-Cores aren't syncronized? (And why are they
out of sync?)

(And yes, 2.6.24.4 is fine... even hpet works there without any
rtc: lost 14 interrupts)
