Boot fails at blinking cursor, upper left corner, after FC11 update

[Philip Greer]

All:
I've just updated my FC11 install on my lenovo T60 laptop. Now when the 
laptop boots, just after the lenovo splash screen, when it attempts to 
boot from the sda drive (sata internal drive) it hangs with a blinking 
underline cursor in the upper left hand corner of the screen. All key 
strokes after that point result in no response, until the buffer is full 
and key strokes cause the system to beep at each key stroke.

I've tried booting off the rescue DVD, which does allow me to see the 
installed system. The latest kernel is 
vmlinuz-2.6.29.6-217.2.3.fc11.i586 and the init ramdisk 
(initrd-2.6.29.6-217.2.3.fc11.i586.img) was updated with the software 
update that I had just performed (today's date and timestamp).

Changing the grub.conf file to no longer have a splash image, have a 
timeout of 30 seconds instead of 0 and commenting out 'hiddenmenu' 
results in no changes, still getting the upper left blinking underline 
cursor, so I can't even get into a grub boot prompt when booting off the 
hard drive.

What are some initial troubleshooting actions that I should attempt? 
Suggestions?

Thanks in advance!

Cheers,
