New 2.6.15-1.1830_FC4 kernel conflict

[Eric Tanguy]

When i try a yum update, i obtain : 
Resolving Dependencies
--> Populating transaction set with selected packages. Please wait.
---> Package kernel.i686 0:2.6.15-1.1830_FC4 set to be installed
---> Package kernel-devel.i686 0:2.6.15-1.1830_FC4 set to be installed
--> Running transaction check
--> Processing Conflict: kernel conflicts udev < 071-0.FC4.1
--> Finished Dependency Resolution
Error: kernel conflicts with udev < 071-0.FC4.1

What's the problem ?
