Re: change from lilo to grub results in kernel panic

Hi!

1) HISTORY
I ran my slackware 9 for years booting with lilo from /dev/hde3 (hde1 being an obsolete Win partition, hde2=swap). The high number of hd is due to hardware configuration of the GA-BX-board having 4 IDE slots, only 3+4 being usable as UDMA...

Last week I put Fedora 5 on /dev/hde1 and changed to grub alongside the installation. Fedora didn't recognise the bootable linux, so I added by hand what I knew from lilo.conf:

2) SITUATION
============================
LILO (extract):

append="hda=ide-scsi"
boot = /dev/hde
image = /boot/vmlinuz
root = /dev/hde3
label = Volkerding
read-only

============================
GRUB:

#boot=/dev/hde
title Fedora Core (2.6.15-1.2054_FC5)
root (hd0,0)
kernel /boot/vmlinuz-2.6.15-1.2054_FC5 ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.15-1.2054_FC5.img
title Slack9
root = /dev/hde3
kernel (hd0,2) /boot/vmlinuz hda=ide-scsi vga=773

============================

3) PROBLEM

Fedora is smoothly booting. Slackware is starting to boot, but ends up with a "kernel panic":

"Please append a correct "root=" boot option
unable to mount root fs on 03:06"

I can still boot the Slackware from a bootdisk/bootable cdrom.
I have seen several discussions adressing similar problems, but they all occurred after recompiling kernels. I did not compile any of the two kernels involved!

So? Any syntax error in my "menu.lst" that I could not identify? Or any other idea?

No syntax, but semantics - the GRUB 'root' clause directs the
file searches in GRUB, not the root device in kernel. You need
to keep 'root=/dev/hde3' in the kernel parameter line.
