Hello, thanks all for your answers.
This is different hardware. Unfortuantely that box went in production,
but I'll see if I can fix another maschine, I have the S3200 Server
board in spare.

I'll try to understand that in a quiet minute, which won't happen before

One thing which is also new to me is an attached IPMI wtachdog. No idea
about IPMI (yet) but maybe the wd-timer is just occupated by BMC/IPMI?!

ipmi0: IPMI device rev. 1, firmware rev. 0.2, version 2.0
ipmi0: Number of channels 2
ipmi0: Attached watchdog
