Yum problem I have not been able to overcome ...

[Prarit Bhargava]

I've been trying to upgrade an FC2 box to FC3.  I've installed the 
appropriate RPMs to do so, however, I keep getting the following error 
during the transaction check:

--> Processing Dependency: librpmio-4.3.so for package: net-snmp
--> Processing Conflict: udev conflicts kernel< 0:2.6
Traceback (most recent call last):
  File "/usr/bin/yum", line 8, in ?
    yummain.main(sys.argv[1:])
  File "/usr/share/yum-cli/yummain.py", line 104, in main
    (result, resultmsgs) = base.buildTransaction()
  File "/usr/lib/python2.3/site-packages/yum/__init__.py", line 174, in 
buildTransaction
    (rescode, restring) = self.resolveDeps()
  File "/usr/lib/python2.3/site-packages/yum/depsolve.py", line 190, in 
resolveDeps
    (checkdep, missing, conflict, errormsgs) = self._processConflict(dep)
  File "/usr/lib/python2.3/site-packages/yum/depsolve.py", line 492, in 
_processConflict
    uplist = self.up.getUpdatesList(name=confname)
UnboundLocalError: local variable 'confname' referenced before assignment

A quick Google on this error indicated that I should remove all 2.4 
kernels from my system -- I did so using "rpm -e" ...

Anyone have any ideas?
