Hi All,

I was trying to install kernel version 2.6.23.1 which I downloaded from kernel.org. After going through the install procedure, my system goes in to kernel panic, with the following errors:

###################################################
mkrootdev: label =/1 not found
mount: error 6 mounting ext3
mount: error 2 mounting none
switchroot: mount failed: 22
mount /initrd/dev failed: 2
kernel panic - not syncing: Attempted to kill init!
####################################################

Following is the system info:

Disto: CentOS 4
Bootloader: GRUB

# Note that you do not have to rerun grub after making changes to this file

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I googled a lot but couldn't solve the problem: Specifically, I compiled in the ext3 fs which was originally set as a module in the .config

I am unable to understand why the label could not be found with the new kernel entry as the same label is being used for the previous kernel as well. Can someone please explain?

If I replace the label with the actual device /dev/sda2, I go ahead with the label error but the mount errors persist.

Any help in this regard will be highly appreciated.

Look for that line in your grub.conf ... delete the "1".

Thanks Simon for your response but that didn't help. Same error was reported this time too:
mkrootdev: label =/ not found
mount: error 6 mounting ext3
mount: error 2 mounting none
.....

Actually, on running the mount -l command, I found the following info:
/dev/sda2 on / type ext3 (rw) [/1]
none on /proc type proc (rw)
none on /sys type sysfs (rw)

which shows that the label is "/1" and not "/".

1. Why is this label not found with new kernel when its running fine with the old kernel?

2. What's the reason for these mount issues?

Compare the grub.conf entries for the new kernel with those for the old one.

Possibly the new kernel or the initrd dosn't have tho drivers for your root partition... could it be SATA? Try remaking the initrd. (see link above).

Problem solved... There was an issue with installation of ATA_PIIX module which was the cause of all problems... Thanks for your support.

Watch more closely, you probably got an error message before that.

What you are looking at is the GRUB terminal. You only get that if there is something wrong with your menu.lst/grub.conf file. There are a lot of different things that could be - the circumstances would help here... my psychic powers suggest a general square beige-ness and round things spinning. Am I close?
