-current build crashing at startup under bhyve (ACPICA?)

[Dustin Marquess <dmarquess%gmail.com@localhost>]

Hello,

I just recently upgraded a VM running under bhyve to a -current build
from ~8 hours ago.  Booting it now instantly crashes at boot right
after ACPICA:

Is this a known issue?

Thanks!
