In your message of: Sat, 24 Feb 2001 09:54:47 CST, you write:

Yes, I am using grub, the buggy bootloader. The relevant chunk of
kernal messages are:

Kernel command line: root=/dev/hda1 mem=327616K
You are dead on, mem= seems a bit small. Forcing mem=320M on the
command line fixes the problem completely.
