--- Comment #2 from John Baldwin <jhb@FreeBSD.org> ---
Hmm, I thought had sent a mail about this earlier, but I guess not.  Are you
able to put DDB in your kernel config and get a db> prompt at all?  If so, a
stack trace would be really helpful.  If not, one thing to try first that m=
ight
help is to get down from 4 CPUs to 2 CPUs.  You can set these hints at the
loader prompt (or in loader.conf) to disable CPUs 2 and 3:

hint.lapic.2.disabled=3D1
hint.lapic.3.disabled=3D1

--=20
