I just upgraded from the 2.4.18bf2.4 kernel, now LinuxOLD on my
LILO menu, to the 2.6.8 .... 686 kernel available from sarge.
Unfortunately the 2.6 kernel gives me the following panic:
VFS: Cannot open root device 2141 or unknown-block(33,65)
Please append a correct "root=" boot option
Kernelpanic: VFS: Unable to mount root fs on unknown-block(33,65)
The computer is a Gateway 500 with a Pentium III at 500 MHZ. I
looked through the man pages for lilo.conf, syslog, and a few others.
I also looked at the source, somewhat briefly, of course, for any
special options for 2.6 kernels that I needed to put into the
lilo.conf file. (I've also downloaded the source code for the 2.6.8
kernel.) The bf2.4 kernel works fine. However, both the 2.4.16-686
and the 2.6.8-2-686 kernels will panic. I'm only concerned about
booting and using the 2.6 kernel, of course.
I am subscribed to the list, but CC's are fine.
What options or docs did I miss? Hopefully, it's just a change to
my lilo.conf file? Although my boot drive is /dev/hde, my root for
Linux is on /dev/hdf1 as you can see from the lilo.conf file. This
Gateway 500 also has Window 98SE on it. I added a second hard drive
and decided to put Debian GNU/Linux 3.0 (woody) on it.
Thank you for any help giving or pointing me to the correct
information!
This is my /boot directory:

# Enable map compaction:
# Tries to merge read requests for adjacent sectors into a single

# You can set a password here, and uncomment the `restricted' lines
# in the image definitions below to make it so that a password must

# standard default boot will not require one.
#
# This will, for instance, prevent anyone with access to the
# console from booting with something like `Linux init=/bin/sh',
# and thus becoming `root' without proper authorization.
#
# Note that if you really need this type of security, you will
# likely also want to use `install-mbr' to reconfigure the MBR
# program, as well as set up your BIOS to disallow booting from
# removable disk or CD-ROM, then put a password on getting into the
# BIOS configuration as well. Please RTFM `install-mbr(8)'.
