Let me reiterate what I consider key facts:

1. my grub setup works __EVERY__ time from a cold start.
2. my grub setup hangs (or never begins to execute?) without any console display __EVERY__ time I try a warm boot (init 6).
3. i have the same problem with two different distributions (FC4/Centos 4.1).

Is there difference between cold and warm boots? In each case, I see the BIOS cycling through the configured boot devices. Does anything happen differently after that?

Or, thinking about it another way, what could different about the state of the system after linux has halted vs just after the power switch is flipped on?

It's also time I disclosed my Grub/disk setup (This one's from CentOS, but the FC4 install creates the same thing).

My fstab:

My Menu.lst (all files referenced exist)

        kernel /boot/vmlinuz-2.6.9-22.EL ro root=LABEL=/ rhgb quiet
        initrd /boot/initrd-2.6.9-22.EL.img

My Grub.conf (identical to menu.list)
