It happened again.  I was running it with the provided patch, but it looks
like the same panic.  The kernel are core will be on leaf:~/crash/4/.

Again, I was messing around with vkernels, and it seemed to crash as the
vkernel was booting (looked like it had just configured the network
interfaces).  Just a reminder that this is the real kernel that's panicing,
not the vkernel.
