Comment 25 for bug 338083

@Nikos:
Here's my menu.lst entry. I've provided a "before" and "after" so you can see the differences (since it's not an Ubuntu-based menu.lst).

Before:
title Gentoo Linux 2.6.30-r1
root (hd0,2)
kernel /boot/vmlinuz-2.6.30-gentoo-r1 root=/dev/ram0 real_root=/dev/shiny/root dolvm
initrd /boot/initramfs-genkernel-x86_64-2.6.30-gentoo-r1

After:
title Gentoo Linux 2.6.30-r1
root (hd0,2)
kernel /boot/vmlinuz-2.6.30-gentoo-r1 root=/dev/ram0 reboot=pci real_root=/dev/shiny/root dolvm
initrd /boot/initramfs-genkernel-x86_64-2.6.30-gentoo-r1

The only difference should be "reboot=pci" after "root=/dev/ram0" on the kernel line.
