Bug 494154

Description of problem:
Shortly after booting my newly installed fedora 11 beta x86_64 system,
this appears in the messages file:

Don't know enough to even guess what might be going on, but despite the
apparent error, I haven't actually noticed anything stop working.

Version-Release number of selected component (if applicable):
kernel 2.6.29-0.258.2.3.rc8.git2.fc11.x86_64

How reproducible:
Every time I boot

Steps to Reproduce:
1.boot system
2.
3.
  
Actual results:
above nonsense

Expected results:
not the above nonsense :-).

Additional info:

Since I see one of the routines in the stack trace has "nic" in
the name, maybe this is network driver? I'm using the onboard
ethernet provided by my nvidia chipset:
