	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 .
