agpart error..

[Robert Hagg]

On my Poweredge 2550, running RH Enterprise v. 4, Linux version 2.6.9-42.ELsmp (bhcompile at hs20-bc1-1.build.redhat.com) (gcc version 3.4.6 20060404
  (Red Hat 3.4.6-2)) #1 SMP
I'm receiving the following warning...I haven't been able to find a fix. Any ideas on where to look to resolve this?
