Are you sure it even tests the full 128GB? Traditionally PAE only
supports 64GB.

At what point exactly? You probably have a serial
console. What are the last lines.

That could well be an ECC error. You can see if mcelog
logs something after reboot (kernel should preserve 
machine check events) 

Or you could switch around the DIMMs of the CPUs for 
testing.
