Hi,
ever since I moved to 2.6.25-rcY (Y should be between 2 and 5!). I've seen several, but really hard-to-catch instant freezes on my AMD64 Athlon X2 4200+ system...
Most of them happend in X.org so at first I thought it had something to do with the NVIDIA module... BUT, one time it froze "a way before" the module could get loaded (and desynced my raid.......).
--- SYSRQ-P revealed that the CPU were looping inside:
smp_64.c native_flush_tlb_others: assembler code: < 1ee: f3 90 pause < 1f0: f6 45 00 03 testb $0x3,0x0(%rbp) < 1f4: 75 f8 jne 1ee <native_flush_tlb_others+0x5f>
also known as: (in C)
while (!cpus_empty(f->flush_cpumask)) cpu_relax();
So... has anyone a good idea what's happening here exactly? Or is there already another topic or even a patch available?
Regards, Chr.
