Public bug reported: After recent kernel upgrade to 2.6.38-3.30, I can no longer boot my system. I have LVM + dm-crypt setup, therefore I need to enter my dm-crypt password during boot. Instead of plymouth, I get just black screen. Even if I start grub2 menu (holding Shift during boot), I just get corrupted screen (garbage), but even selecting older kernel on menu does not seem to help much (does not recover).
The only way I was able to workaround the problem was to boot from recovery CD, chroot to my / partition and remove linux- image-2.6.38-3-generic package and reinstall grub (grub-install /dev/sda) in order to get older vmlinuz.
