If it's not memory related (test this memory in another system) then it is probably a motherboard failure. I've seen weird symptoms where the system will boot fine, but once the Linux kernel begins to build its cache it triggers a lock up/throws an exception.

We've shipped them back, and they wind up replacing the m/b.
