Thanks, Matthew. I thought of the same thing, although I'd suggested he
try to boot into a previous kernel. His problem is that the boot gets
stuck right before the blue splash screen, when the word "grub" briefly
flashes in the upper left hand corner of the screen - right at that
point, his machine just stops. Any other suggestions?
*Before* the first splash screen? Then apparently GRUB is hosed. So I
would try:
(1) Boot from Rescue CD. It will find your installation and offer to
mount it under /mnt/sysimage. Mount it r/w.
(2) chroot /mnt/sysimage
(3) rpm -e the newest kernel. Verify that /etc/grub.conf makes sense.
(4) Reboot into the latest still-installed kernel.
(5) Run kudzu, then update the kernel again.
If (4) fails, post your /etc/grub.conf (you can read it if you carry out
(1)-(3) again).
