D'oh

Ok, IPMI does not work remotely, after removing it does and still after 
rescanning (netconsole not loaded for the time being). At this point I ran 
ethtool -S for both interfaces as well as ethreg (suffix afterRescan).

then I only ran dhclient:
dhclient3 -pf /var/run/dhclient.eth0.pid -lf 
/var/lib/dhcp3/dhclient.eth0.leases eth0

and afterwards the IPMI connectivity was gone again.

Status files after this are also attached, suffix afterDHClient

Does this help?

Cheers

Carsten
