e2fsck dies with signal 11

[Theodore Ts'o]

The dmesg indicates that the kernel trapped a general protection fault
(GPF) in kernel space.  So this looks like some kind of kernel bug
which was triggered by e2fsck.  Unfortunately the EIP is invalid, so
it's hard to track down what might have caused it.  If this is
repeatable, I'd suggest using strace so we can see what e2fsck was
requesting of the kernel right before it triggered the kernel GPF
which killed the process.
