Hmm.

My main desktop just had a reboot failure - it just got stuck at the
end, not powering down, and not rebooting like it should have.

This is *not* necessarily the pull that caused it, but 8f55cea410db
rebooted cleanly, and 1a13c0b181f2 did not. That implies that it's one
of your pull requests. The pulls I did in between are:

 - scheduler (with the dyntick and cputime accounting)

 - smp-hotplug-for-linus: stop_machine preparatory patches from Thomas..

 - timers-core-for-linus. Hmm..

 - x86-apic-for-linus: certainly possibly causing problems at shutdown..

 - x86-asm-for-linus: sounds unlikely, but who knows..

 - x86-boot-for-linus: shouldn't affect shutdown, but..

 - x86-build-for-linus: _really_ shouldn't affect shutdown..

 - x86-cleanups-for-linus: unlikely

 - x86-hyperv-for-linus: no, not a hyperv user ;)

 - x86-platform-for-linus: rebooting is a platform thing, but none of
this seems relevant

 - x86-uv-for-linus: not likely relevant.

I'm not going to bisect it right now, hoping that somebody goes "Hmm,
maybe it's xyzzy". And maybe it was just a one-time event, but I don't
recall having had that whole "reboot fails" case on this machine
before. Any ideas?
