F12 won't boot after image restored

[barry yu]

I made an image of F12 32bit / with partimage a week ago and I used it 
to restore the partition, partimage reported restoration successful, 
when I reboot and to start the Fedora 12, here is what displayed and 
stuck there;
    [drm:drm_rmfb]*tried to remove a fb that we didn't own
    boot has failed, sleeping forever.
What happened and how to fix it?
