While not a complete definitative hardware test it can report other hardware issues that memtest86+ misses and it can be run on line in multiuser mode and via cron . Thanks for suggesting this. I have a question, however. Let's say 'mcelog --daemon' runs and encounters some MCE and logs it. Wouldn't this record be lost during the subsequent ungraceful (poweroff) reboot? Nonfatal MCEs, if any, will stay but what about the fatal one? Yuri
