probably not the kernel, you might have installed some package since 
your previous reboot and you're just seeing the messages now
I know I saw this with a rebuilt libnjb from FC7

check /var/log/messages, you should see what the message was.
I suspect udevd stuff like: unknown key 'ATTRS{idVendor}'

Then grep the string in /etc/udev/rules.d/* to find the culprit

If you have eg some ATTRS{idVendor} you might try replacing them with 
SYSFS{idVendor}
