It's not able to find the root partition. Make sure: your LILO config
has the right parameters for root volume, your kernel has drivers for
the root hard drive device, the root hard drive device is plugged in
correctly (master not slave, primary not secondary controller, etc.) and
so on. If that doesn't work, boot the kernel by pressing "ALT" at the
LILO prompt and appending a "root=/dev/hda1" (or whatever appropriate)
to your kernel boot command.
The numbers are the major/minor device the kernel is looking at to find
the root partition. In this case major==3, minor==2 euqals hda2.
Next time you can just browse through .../src/linux/fs/super.c and
figure it out... ;)
