Benjamin,
Can you also include the network statistics, it may helpful to know
exactly what type of errors these are:
ethtool -S em1
Are you in a position to change the cable?
I see this is a Supermicro, does the machine have a IPMI card using the
same IP address by any chance ?

I had no trouble with panics booting new CR kernel either, but detecting =
my PCI-e parallel port =

has given even any clue related to it. Maybe this is the difference =
between RHEL and CentOS. If I was a RHEL licensed user, RedHat support =
staff at least would answer saying anything.
