After updating bios no more crashes happened, i tested it many times on heavy HDD IO loads, with many kernels (including CONFIG_PREEMPT kernels). But now if enable "Cool'n' Quiet" option in bios, CONFIG_PREEMPT_VOLUNTARY kernel with passed "nosmp" at boot time, crashes during boot process with kernel panic, while CONFIG_PREEMPT kernlel without "nosmp" works fine - but it is another story i think, should not be related with the crashes when it was old bios, and i think it is probably "nosmp" the reason. (i have never changed cpu frequency of this cpu at all) When "Cool'n' Quiet" is disabled, the system works perfectly adequately with all kind of kernels i tried. Except that this warning message in dmesg still appears (if it is problem at all). I put here this message for "nosmp" case as well, kernel is 3.5.2:
