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

La referencia de la Duma a la anexión de la RDA, en este caso al contrario con la Crimlía sin
referéndum, no solamente tiene gracia sino da en el blanco.-
