Version-Release number of selected component (if applicable):
kernel 2.6.17-1.2630.fc6



How reproducible:
Bootup using livecd generated by Kadishi and you should see the message with bug
right before it loads udev and then the other services start appropriately.  


Steps to Reproduce:
1. Boot up computer load live cd generated by kadishi and/or install FC6 Test
2/3 and it should be the same I suppose
2. Bug message will show as the livecd is loading.
3. System boots fine most things work fine, I do not know how this bug affects
the system as a whole.  
  
Actual results:
