Public bug reported:

Binary package hint: grub2

I updated my karmic installation on August 1th and grub suddenly stopped
to work. When I start my computer, grub only shows white text on black
background : "GNU Grub version 1.96 [Minimal Bash-like line editing is
supported..." and it stays there definitively and don't react to any
keyboard key. That didn't give me any choices but to reset my computer
and to install Grub 0.96 on a USB key to boot my computer.

Grub is installed on the MBR of my first hard disk on the first ext2
partitions, which is mounted in /root by karmic which is installed on a
mdadm RAID-0 array.

When I rebooted for the first time, ubuntu detected a unclean shutdown
for /dev/sda1 which is the grub /boot mount point. The computer has
never been stopped incorrectly except at GRUB because it stalled so it's
unsure if the ext2 filesystem was unclean before or after grub started
to have problems.

Reinstalling grub with update-grub2 or from the recovery menu, Do a fsck
on /dev/sda1, Reinstalling grub-pc or downgrading grub-pc to
1.96+20090611-1ubuntu3, changing /dev/sda1 to use ext3 instead of ext2
and updating /boot/grub/grub.cfg didn't change anything.

So I wonder if this has something to do with filesystem corruption as
/boot/grub files does not seem to be replaced on update and because
downgrading does not seem to have any effects.
