_Every_ time I have tried to trace a bit-flip oops like that in
find_buffer, it has turned out to be hardware. find_buffer seems
to be about the most sensitive place in the kernel to that sort of
error: the buffer cache code walks its linked lists a lot more than
most other places in the kernel do, in my experience.
