Most of the times I have seen signal 11 in the past, it turned out to be bad
memory. Once I saw it with a bad motherboard. Another time, it was a bad
stick of RAM. The bad stick was a really hard one to track down as you
needed to have something really finicky get put at that address before
Damn!

last three crashes:
