dmesg from failed boot

I firt saw this in the kernel 2.6.30-8 from Ubuntu Karmic.
Afer that I have upgraded to 2.6.30-9 which has caused same problem.
Now I wanted to try vanila git kernel with radeon KMS so I compiled my own
kernel from git. Today I saw it first time also with this kernel.

What happens:
1. I make cold boot or restart
2. Computer boots normaly except all USB ports are dead
3. dmesg shows general protection error caused by khubd

This problem doen't happen even nearly every boot. I would give around 20%
chance for khubd failure without collecting statistics.
