CC'ing Jack Vogel of Intel, as this looks like it could be something the em(4) driver might be tickling. I do see it in the stack trace shortly before the crash. In the interim, can you please provide output from the following command: # pciconf -lbcv And include only the entries relevant to your emX devices. As for the "the server refuses to auto-reboot": that may be a separate problem. You might try toggling the hw.acpi.disable_on_reboot and hw.acpi.handle_reboot sysctls (check what values they have on your system first) to see if there's any improvement.
