Comment 36 for bug 203537

Same issue here, also with amd64 and nvidia-glx-new running hardy.

After hibernating, system locked and then grub error 17... my first partition became unmountable

Fortunately I was very lucky and was able to recover the partition with

e2fsck dev/sda1

without even a file in Lost+found....

Hope a fix for this will be soon available!
