Can't boot after upgrading to 11.1RC1

[chgentso]

Hello, I have a problem with my openSUSE installation.

I tried to upgrade (from openSUSE 11) by manually changing all repositories to 11.1 ones. The upgrade process went smoothly except a kvm related package which failed to upgrade (but I suspect shouldn't be that critical).

After the reboot though, when the kernel is loading, it shows something like
waiting for device /dev/disk/by-id/SATA(root id) to appear..... not found.
At that point it shows a [Y/n] decision about whether to skip the problem (or sth like that) but the keyboard is not responsive (even the Caps lock or F-lock keys do not change any LEDs).

So, I suspect that some modules are not loaded. But as for which and why (and most importantly, how I can fix it) I am at a loss.

So, if anybody has any ideas about that... PLEASE reply.

Thanks in advance

EDIT: I must be blind or something. Right above the previous line, there was the source error:
FATAL: could not load /lib/modules/2.6.27.7-4-pae/modules.dep: File does not exist.

But as I can see, the file DOES exist! Any suggestions?

Reinstall the older system then download and install 11.1 correctly.

When you install do a full install and tell the installer not to format the partition that contains the /home directory when you come to the partition scheme. Sust be sure it is mounted as /home. Also be sure that the current root partition is correct and marked to be reformatted. This will preserve your settings and personal data.

Thank you for the response, but I solved the problem finally. Turns out a kernel package wasn't properly installed, so the initrd wasn't good and thus the problems.

If someone gets bit by that too:
Download the kernel rpms somewhere
From a live or installation CD/DVD go to a root console
Mount your root partition and bind /proc /dev and /sys there
Mount the partition with the rpms and copy them to the mounted root partition
chroot into the root partition
rpm -qa | grep kernel and remove any kernel packages
rpm -i kernel-packages-you-downloaded

Something like that.
Again though, thanks for the reply gogalthorp!
