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
# 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.
For Jack -- the core/stack trace, and dmesg are at the below URL as
