[CentOS] poweredge 1950 hangs at starting udev

Hi all,

I have a PowerEdge 1950 that was acting weird. Network connectivity was only performing at a quarter of what was expected (if that). Even if I scp'd something to localhost it would perform poorly. Rather than fight with it, I just decided to reload it. It was running 5.3, and it is now running 5.4. However, when I go to boot it gets stuck at starting udev. If I let it sit long enough it will then give me errors with something along the lines of: Dazed and confused, but trying to continue Uhhuh. NMI received for unknown reason 00 Do you have a strange power saving mode enabled?

Wondering if anyone has an idea..

Thanks,

Ryan
