root=LABEL=/ seems to be implemented by RedHat specific patch.

Sanity check: Are you _really_ using it? When you get the grub boot
menu, press `e' and inspect what grub is about to execute.

Sanity check: Is what you wrote the whole and unmodified content of your
grub.conf? Because IIRC each menu section must end in `boot' command.

Sanity check: grub.conf? My grub definitely calls it menu.lst

It's not a matter of EXT3. If it was, the error would end in 03:05
(major:minor number of the device it failed to read). But since it ends
in 00:00 it was not able to make sense from what was passed as root=
