I googled for it, seems to be related to a known FreeBSD bug in powerd when used with Atom dual-core CPU. I disabled powerd, so far so good. Please, make sure you include the fix before going STABLE.

Hi,
I can confirm this report. Different motherboard here but same processor.
Version: 0.7.1 Shere (revision 4944)
Platform: i386-embedded on Intel(R) Atom(TM) CPU 330 @ 1.60GHz
Motherboard: D945GCLF2

With powerd the MTBF is 12 hours. without powerd I had no crashes so far in 15 days uptime
