Hi there,
You got a com port available? And a laptop or other computer with a com
port? If so, change your grub like this:
title Fedora 8 (2.6.23.15)
root (hd0,0)
kernel /vmlinuz-2.6.23.15 ro root=/dev/md1 console=tty0
console=ttyS0,115200
initrd /initrd-2.6.23.15.img
So the kernel is also pumping the information via the first com port.
Start minicom at the other machine, select right setting for baudrate
115200 and voila. You will see output, even when it crashes.
This is really then the only way to see if the kernel is really crashing
at something. I have the luxery here to have console servers with buffers.
So if a machine crashes, I can read the buffer of the output, and see what
happened.
Good luck!
Greetings,
Jim.

CTRL-ALT-F1 is working. I believe this is a kernel panic.
