Console stops scrolling

[Gordon Hay]

Booting FC5, messages populate screen, scrolling normally until the
following error occurs:
        PCI: Probing PCI hardware
        PCI: failed to allocate mem resource #6 at 1000000 at 42000000 for
        0000:01:06.0
        PCI: Bridge for 0000:00:0d.0
        
At this point the cursor is stuck at bottom left and as far as I can
tell is unmovable.  The screen no longer scrolls, and the console is
unusable.  

The system appears to boot OK, however: it's accessible via SSH and
seems fine.

Is there a way to "unlock" this frozen console?

Also, if anyone knows what the PCI messages are actually trying to tell
me, I'd be grateful....
