Suspect number one is the device overheating. The shutdown is triggered by the EC. I don't know how you can enable ACPI debug output on BSD though. On linux, it would be "echo 1 > /sys/module/acpi/parameters/aml_debug_output", so whatever the FreeBSD equivalent of that is.
hw.acpi.verbose=1 would be a start. ...
Thanks for all the hints.
As I said, the events are sporadic, seldom, but complete power-off (like as you would cut the cable from the motherboard). Of course the system has no chance to write anything to /var/log/messages or console.
My hope while writing to coreboot@ was to get a pointer to the list of open ore solved issues within coreboot and/or SeaBIOS to see if this issue is somewhat known, solved or could be related to some known or solved issue. Where can I find such a list which is normally (as we do in my company) attached to the Release Notes of a new version of software.
Thanks in advance
Matthias
