CURRENT, as of recent Revision 246285 (see below) fails and
crashes/reboots on an Ivy-Bridge platform (see below). Since the box
does not have debugging switched on (not yet, will do eventually
Monday), Last thing I see on screen is

p4tcc3: <CPU Frequency Thermal Control> on cpu3

then the system run dark and reboots without any notice (kernel doesn't
have debugging switched on so far, will do this after Monday).

The box is running quite well with

FreeBSD 10.0-CURRENT #1 r246222: Fri Feb  1 23:13:28 CET 2013 (amd64)

fail. Is there a known issue with hardware like shown below? I have a
bunch of more modern Sandy- and Ivy-Bridge Intel driven boxes I'd like
to update next week (they run CURRENT as well) and I'm not sure by now
to do so.

The crash occurs with a GENERIC kernel as well as with the custom kernel
(working output is the custom kernel).
