Hello All , Does anoyone know howto identify a cause for these(*) ? Or of any tools to help in the identification of the cause ? So far the Machine checks only happen when I am running bonnie++ against my software raid6 array .
I have done everything I know to do to attempt to ascertain what is causing the machine checks . ie: 1) memtest86+ for days , no errors . 2) cpuburnP6 , The tests run were 'cpuburnP6 E' & 'cpuburnP6 H' for ~ 60 minutes each . All CPU's & HT were at 96+<->100% for 60+ Minutes , no excessive heating or lockups . In single user mode of course . I know cpuburn is old but it can excersize the comms between l1 & cpu & l1 & l2 -> cpu if done right .
(*) CPU 5: Machine Check Exception: 0000000000000004 CPU 4: Machine Check Exception: 0000000000000004 Kernel panic - not syncing: Unable to continue <system reboots>
root@(none):~ # uname -a Linux (none) 2.6.21.5 #1 SMP Fri Jun 15 04:37:23 UTC 2007 i686 pentium4 i386 GNU/Linux
Complete serial console log of a boot to single user mode is here .
