This indicates that the kernel is not able to find the root partition.
and that the kernel has already booted - most likely not a problem with
GRUB.

Your partition table suggests that there are two different partitions
for '/boot'
and '/'. The GRUB loads the kernel from '/boot' which is (hd0,0) but the
kernel is unable to find the '/' partition. You may pass it using the
parameter
root=/dev/hda3.

That should work.

It may not work. As he said in the original message, he found lot's of other
people with that problem, including... myself. Since 2.6.4 I can't boot any 2.6
kernel, allways with that Kernel panic. I've tried several things, including
using the root=/dev/hda3 parameter, and, at the time, I've raised the issue
here on LKML, but no conclusion has been reached.

A search on LKML led me to this:

have you tried removing the initrd entry in GRUB.
In most cases you can safely do away with it. That would
atleast make sure the problem is not with the initrd.

Yes, I did it.
I'm actually using lilo, but I've tried with both.
