[Kernel Panic] [FIXED] After system update - Can't find filesystem

Hi guys I got kernel panic
After the pacman -Suy my arch system can't boot!
The error is:

loading root filesystem module
Attempting to create root 
device /dev/hda4 uknown

ERROR root fs acnnot detected
Try using the roofstype=kernel parameter...

Any ideas?

Thank you

Re: [Kernel Panic] [FIXED] After system update - Can't find filesystem

Well, I have the same question - how do I find out which version worked for me? Is there a history build into pacman?

Or shall I just search /var/cache/pacman/pkg/ for one that suits me? ^^

Yes. For my situation I think that I have 2.6.23...

You can try pacman -U /var/cache/pacman/pkg/kernel and press tab to see what files you have in the kernel folder. Choose the kernel you want.

Now I am rolling back to 2.6.23 and I will see and post here If fixed.

Edited: Fixed... But a question:

How can I update with pacman -Suy and not the kernel be panic ?
I think that the problem created from the kernel update...

Re: [Kernel Panic] [FIXED] After system update - Can't find filesystem

You most likely don't need to change the kernel version, it's usually sufficient to regenerate kernel boot image with "mkinitcpio -p kernel26".  If you're using any exotic filesystem as root it's probably also a good idea to add it to the "MODULES" array in /etc/mkinitcpio.conf to make sure that the module gets loaded into the boot image.
