With todays upgrade I had to fsck my Maverick-Installation again:
sudo fsck /dev/sdaX
fsck from util-linux-ng 2.17.2
e2fsck 1.41.14 (22-Dec-2010)
/dev/sdaX: stelle das Journal wieder her
Bereinige verwaist Inode 27918417 (uid=0, gid=0, mode=0100644, size=2719432)
Afterwards I was able to recover Maverick within GRUB2 via sudo update-grub.
