RE: Failing boot - Kernel panic

[marvilleke <marvilleke@yahoo.co.uk>]

Hi Mr. Terpstra, 

I also had these problems however, you need to provide
more info regarding your problem. 

Things which should me installed
kernel-package => this package contains a manual for
installing 2.6 series kernel which is quite extensive
and good to understand. 

so do something with:
apt-get install kernel-package 

At first sight it looks that you can not mount your
root filesystem. 
please check if your initrd is properly made. 
system.map, config file  are pointed correctly 
don not forget to run: lilo -v -v -v (-v => for more
debuggin info)



Question: " (by the way, is there any way to get a log
of all the messages from a failed boot?)" 

Answer: yes, please check: /var/log/syslog


have fun, 

Marvilleke


I'm getting an error on startup that causes the system
to halt before fully booting, and would like some help
figuring out what exactly is wrong and how to fix it
:) Here are what seem to be the applicable lines:

  request_module[block-major-3]: Root fs not mounted
  VFS: Cannot open root device "341" or 03:41
  Please append a correct "root=" boot option
  Kernel panic: VFS: Unable to mount root fs on 03:41


(by the way, is there any way to get a log of all the
messages from a failed boot? I had to copy these out
by hand)

I'm using lilo as my boot manager for a multi-os
system, with the operating systems occupying two
separate physical drives. I would like to put lilo on
the mbr of the first drive, and have it able to boot
windows from hda2(vfat) --which it currently does
without a problem-- and my Debian installation from
hdb1(ext2). hda1 etc are currently being used by
another installation of Debian which I'm going to
remove once this one's working.
The error seems to occur AFTER lilo has passed control
to the kernel, but the part about appending a "root="
option sounds like a lilo issue to me, so here's my
lilo.conf (minus the comment lines):

  lba32
  boot=/dev/hda
  root=/dev/hdb1


  install=/boot/boot-menu.b
  map=/boot/map
  delay=20
  menu-title=" Booting FriedFish on... "
  vga=normal


default=Linux

  image=/vmlinuz
        label=Linux
        read-only


  image=/vmlinuz.old
        label=LinuxOLD
        read-only
        optional


  other=/dev/hda2
        label=Windows


I can't see anything wrong here. Is it possible that
the other Debian installation's copy of lilo is
messing something up?

I should probably also mention that hdb is a new drive
I just purchased. Is it possible there is something
wrong with the drive itself? (a quick google search
for "kernel panic VFS" seemed to bring up a fair
number of dead harddrive scenarios..)

The system was booting properly when I first installed
Debian on the new drive and hadn't yet tweaked lilo.
I'm not sure if this problem started immediately after
this or not though, as I was doing a lot of switching
around with boot disks for a while there. Besides
changing around lilo's configuration, I've also just
recently removed kde and installed Gnome1.4,
complimented by a few gnome2 libraries that dselect
thought were a good idea. My boot disks still work
fine (although they are incredibly slow)

Is there any other information about my
system/history/etc that would be helpful?

Sincerely,
 --Maxwell Terpstra
