You've got 0x00000800 in %eax, and the oops is on a field access
for a structure at that address. There's a null, list-terminating
pointer in the buffer chains which has had a single bit flipped to
one. This is nearly always bad ram, but it can also be cache or
an overheating CPU. It definitely sounds like hardware, though.
