Machine Check Exception: 0...04

["Mr. James W. Laferriere" <babydr@baby-dragons.com>]

	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 .
