Please also check:


(that file may be in /etc rather than /lib, but not sure about Fedora 

Also as this is an upgrade, I'd recommend checking that you don't have 
any orphaned files still installed that were not automatically removed. 
You can use a yum utility to find orphaned packages but I forget the 
syntax off-hand. I'm sure a quick search will find the necessary info.

Then you could veryify each rule in /etc/udev/rules.d and 
/lib/udev/rules.d via rpm -qf and rpm -V commands.

That way you can likely nail down where the problem lies with the udev 

That may or may not actually help in the case of the PA stuff. It could 
still be the kernel that is causing you problems.
