I had a slightly different problem with my AMD XP 1700+ processor m/c. My m/c used to hang at Activating Swap Partitions or at Finding Module Dependencies. This was happening after installing RH 9.0, Fedora Core 1 and Redhat Enterprise Edition 3 (RHEL 3).
I tried all possible combinations of words while searching in google but had not found a solution till today (AFTER 1 year!!)
Finally in this forum I found the answer needed.
adding "apm=off" at the boot line.
# vi /etc/grub.conf or # vi /boot/grub/grub.conf
title Red Hat Linux (2.4.20-8)
kernel /vmlinuz-2.4.20-8 ro root=LABEL=/ hdd=ide-scsi apm=off
THANKS A MILLION ANDREW FOR SUGGESTING THIS SOLN. AFTER 1 YEAR I CAN WORK ON MY LINUX AMD PC.
