One of these is probably your issue (from the RHEL-4 kernel changelog): * Tue Oct 23 2007 Jason Baron <jbaron at redhat.com> [2.6.9-65] -forcedeth: fix nic poll that causes panics on some hardware (Andy Gospodarek) [337291] <snip> * Mon Jun 18 2007 Jason Baron <jbaron at redhat.com> [2.6.9-55.9] -forcedeth: update to driver version 0.60 (Andy Gospodarek) [221910] I would make SURE that I had the latest BIOS (firmware) update for the motherboard as those routinely fix problems with built on NICs and built on controllers.
