F10 hard lock issue

[Richard Shaw]

I just upgraded my wife's laptop to F10 from F9 using preupgrade.
other than not having enough free space (had to make some) the install
went perfectly. Now I'm having a lockup issue.

When it first starts everything hard locks. Then I hear the DvD head
moving, some time later I can turn the caps lock on and off but there
is a significant delay. Also, the mouse cursor works but nothing else
does. I can't do Ctl-Alt-Backspace or get to any of the virtual
terminals. Scanning through /var/log/messages I don't see anything
useful. Any ideas on where to start? This thing was rock solid under
F9.

Compaq laptop Turion 64 1.8GHz w/ Radeon 200M chipset. 1GB system ram.
Broadcom wireless using native driver.

Thanks,
Richard
