Weird Kernel Panic (more or less solved)

trapdoor · 2006-03-20 09:42:14

Hey guys,

When I tried booting this morning i got a Kernel Panic.

I tried using archck and the stock kernel, but both give me the same error

VFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I chrooted into hda3 and this works perfectly, so any ideas?[/code]

Did you run an fsck on /dev/hda3?

Had the same problem once. I forgot that my HD was connected to a kind of SATA controller.. Try sda3 if you are unsure about that.

It worked for like 2 Years with hda3 so i don't think it changes over night

Who knows. Have you updated udev or your kernel lately?

trapdoor · 2006-03-20 14:12:22

Yep, i did... but i think the problem has something to do with initramfs.

So what i did is, i put in the arch 0.7 installation cd and chrootet into /dev/hda3 and did mkinitramfs, but it always says that /sys/ is not mounted, so how do i do that?

Or is there an easier way, maybe via live cd to fix this?

MAC!EK · 2006-03-20 14:23:04

Does /sys directory exist?
Mayby add initrd-full to lilo as an additional boot label?

trapdoor · 2006-03-20 14:38:38

It exists but it isn't mounted, i added initramfs-full to grub, but nothing happened

Sigi · 2006-03-20 14:54:50

Can you post your /etc/fstab and your /boot/grub/menu.lst or lilo.conf?

trapdoor · 2006-03-20 21:47:05

Here we go with fstab and menu.conf

#
# /etc/fstab: static file system information
#
# <file system>        <dir>         <type>    <options>          <dump> <pass>
none                   /dev/pts      devpts    defaults            0      0
none                   /dev/shm      tmpfs     defaults            0      0

/dev/hdb1 /home/trapdoor/data reiserfs user 0 0
/dev/hda1              /mnt/win2         vfat   user

and

# (0) Arch Linux

kernel /boot/vmlinuz26archck root=/dev/hda3 initrd /boot/initramfs-full.img ro

title Windows XP
rootnoverify (hd0,0)
chainloader +1
makeactive

Hope this wil help in any way

Sigi · 2006-03-20 22:09:47

Try this, don't know if it helps:

# (0) Arch Linux
title  Arch Linux  [/boot/vmlinuz26]
root   (hd0,2)
kernel /boot/vmlinuz26archck root=/dev/hda3 ro
initrd /boot/initramfs-2.6.15-archck.img

Cheers Sigi

I tried it tomorrow, but without any positive result.

Are there any other suggestions? If not, i will backup all my data and reinstall arch.

Sigi · 2006-03-21 08:59:06

What do you mean by "without any positive result"?
Still the same error? Do you have the newest version of mkinitramfs installed?

Cheers Sigi

trapdoor · 2006-03-22 20:42:59

I reinstalled my system and now everything works perfect again, so thanks for your help anyway. I'll mark this thing solved now.
