joel is right. See FAQ #17.

yes. LPMC is usually a recoverable memory parity error.
ISR/IOR is the virtual address that was accessed.
Since this is kernel space (ISR==0), I think you can just
drop the leading 1 for the physical address.

Try pulling half the memory and see if the trap goes away.
Or replace all the memory if you have spares.
