================================================================================================== I thought this is a memory problem, we have changed memory and memtest86 runs clean, but the problem is still there. The problem can be reproduced by running bonnie++ benchmark. Is it possible that this is a disk problem? Thank you Evgeniy
What motherboard do you have? You might want to play
with BIOS memory settings, like "node interleave", etc
Are both CPUs dicovered (cat /proc/cpuinfo)?

Both CPU are discovered correctly.
I tried disabling node interleaving, but that does not help unfortunately.
