I'm using yum update to update my rawhide system. It has the following kernel characteristics. uname -a Linux localhost.localdomain 2.6.23-0.195.rc7.git3.fc8 #1 SMP Sat Sep 22 08:20:01 EDT 2007 i686 athlon i386 GNU/Linux I see that kernel.i586 is in the update list. This seems like it might be a problem. Shades of the Fedora Core 6 problem.
