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.
Note also that there is similar (maybe related) bug 718044
