Re: not booting after kernel upgrade

Re: not booting after kernel upgrade

I had the same problem on my Notebook which still has an IDE hdd. It looks like they changed /dev/sd** for any hdds, to /dev/hd** for IDE disks and /dev/sd** for SATA disks, like it was before.

Try changing /dev/sda8 to /dev/hda8 in your /boot/grub/menu.lst and in /etc/fstab.

Re: not booting after kernel upgrade

I don't know if you ever got this problem solved, but I didn't after trying every "fix" I could find on these forums.  I ended up rolling back to the 2.5.24 kernel and the appropriate setup to make it work.  It doesn't seem like anyone has figured out where the general problem is yet.

This bug report sounds eerily similar to the problem I experienced, except I use ext3...

I have the same problem, also with ext3. Can you give me pointers on how to roll back to the old kernel? I come from the dpkg world and it usually leaves old kernels around in case the new one fails to boot the machine. I tried the following steps:
1. boot with knoppix
2. mount sda4 (/)
3. mount sda2 (/boot)
4. mount --bind /sys /mnt/sda4/sys
5. mkinitcpio -k 2.6.25-ARCH -g /boot/kernel26.img

and now I'm getting a kernel panic. Here's a typeup of the error messages:

: Running Hook [keymap]
: Loading keymap...done.
: Running Hook [filesystems]
: Loading root filesystem module...ext3
Waiting for devices to settle...done.
: Initramfs completed - control passing to kinit
P-Config: no devices to configure
Waiting 0 s before mounting root device....
init: Cannot open root device sda4(8,4)
init: init not found!
kernel panic - not syncing: Attempted to kill init!

5. mkinitcpio -k 2.6.25-ARCH -g /boot/kernel26.img

Never mind, I added
4.1 mount --bind /dev/ /mnt/sda4/dev/
4.2 mount --bind /proc/ /mnt/sda4/proc/

reinstalled kernel26 and mkinitcpio, and rebuilt the kernel. Things are now working properly.

Sorry for the delay replying.  Looks like you got it fixed though.  Congrats.

Did you issue command nr 5 inside of knoppix? It doesn't work here. Help, I want my system back!

EDIT: 4.5 chroot /mnt/sda4
