kernel update: kernel panic, I cant fix

HI
last nigth I do Pacman -Syu, but in the morning i cant boot:

reiserfs: version magic '2.6.17-beyond-SMP preempt mod_unload 686 gcc-4.1' should be '2.6.19-beyond SMP preempt mpd_unload 686 REGPARM'
mount: Mounting /dev/root on /new_root failed no such device
mount: Mounting none on /new_root /initrd failed no such file or directory
switch_root: bad newroot /new_root
Kernel panic - not syncing: Attemp to kill init

My grub:

root (hd 0,0)
kernel /vmlinuz26beyond root=/dev/hda3 ro video=vesafb:ywrap, mtrr, 1024x768 -32@60 splash=verbose theme:darch
initrd /initramfsfs-beyond.img

I try to edit the grub in "root=/dev/hda3" for 'root=/dev/sda3', no results.
My laptop is my work machine, i lost all morning try to fix, i have a sencible data too in my HD..

any suggestion or help must be apreciated
thanks in advance

Re: kernel update: kernel panic, I cant fix

You upgraded from 2.6.17 to 2.6.19 by any chance?

When you update the Archlinux kernel to 2.6.18, make sure
                   that you changed the initrd setting in your bootloader
                   (/boot/grub/menu.lst or /etc/lilo.conf). The filename is
                   kernel26.img instead of initrd26.img for kernel26 and
                   kernel26beyond.img for kernel26beyond. For troubleshooting
                   and advanced setup, see
                   http://wiki.archlinux.org/index.php/Mkinitcpio

Re: kernel update: kernel panic, I cant fix

The problem is that your reiserfs module (at least - possibly others too) is from the 2.6.17 kernel, and is therefore incompatible with your new 2.6.19 kernel. How this happened I couldn't say, but I would suggest reinstalling the kernel package, and watching the output very carefully for any messages.

If a reinstall doesn't fix it, you'll need to figure out how this might have happened - a root around in /lib/modules would be a good start. You may need to manually delete old modules, and/or run depmod again.

Re: kernel update: kernel panic, I cant fix

This is still the old obsolete initramfs image. Grub's initrd line needs to be changed to kernel26beyond.img.
