What did you find when you loaded the module with gdb as Neil suggested? 
If the code in the module doesn't match the code in memory you have a 
hardware error. memtest86 is a useful tool, but it is not a definitive 
test because it doesn't use all CPUs and do i/o at the same time to load 
the memory bus.

I would pull out half my memory and retest. If it still fails I would 
swap to the other half of memory. If that didn't show a change I would 
check that the code in the module is what Neil showed in his last 
message (I assume you already have), and then reseat all of the cables, etc.

I agree with Neil:
