Crashes with the current -HEAD

[C. Jayachandran]

I'm seeing crashes like the one below when I do a 'make -j16
buildworld' in the current HEAD.  This is without SMP enabled and
without any of the XLR smp changes.

buildworld used to work on XLR with earlier kernels - the last good
kernel I have is around r206712.  Any idea what can be causing this?

Thanks,
JC.
