Version-Release number of selected component (if applicable):
2.6.29-0.93.rc3.git10.fc11.x86_64

How reproducible:
Seems to happen on first "serious" network access (dhcp doesn't trigger it) after every reboot.

Steps to Reproduce:
1.  use above kernel
2.  reboot
3.  access network (so far scp, yum update both 100%)
  
Actual results:
System seems to continue to work fine.  Have seen some other warning messages, not sure if they're related or general rawhideness.

Expected results:
No warning messages.

Additional info:
attaching full /var/log/messages in case other stuff in there is useful.
