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 .

Hopefully more useful information . Again only if I am doing any HEAVY
disk activity ie: bonnie++ .
I am not able to find a tool to disassamble the EIP: portion of the
CPU 4: output .
