Bug#567637: grub-probe: error: unknown filesystem -- fails to boot from ext3

Package: grub-pc
Version: 1.98~20100128-1
Severity: grave
Justification: renders package unusable
After an update from grub-pc_1.98~20100115-1_i386.deb (current testing version) to
grub-pc_1.98~20100128-1_i386.deb, the system does not boot anymore; grub says
"unknown filesystem" and drop me to the rescue> shell, where I cannot do
anything (no "setup" or "boot")
The following is my fdisk -l:
----
Device Boot Start End Blocks Id System
/dev/hda1 1 784 6297448+ 8e Linux LVM
/dev/hda2 785 3844 24579450 8e Linux LVM
/dev/hda3 * 5884 7230 10819777+ 83 Linux
/dev/hda4 3845 5883 16378267+ 5 Extended
/dev/hda5 3845 3907 506016 82 Linux swap / Solaris
/dev/hda6 3908 5732 14659281 8e Linux LVM
----
/ is on /dev/hda3
Unfortunately after the upgrade grub-probe is unable to find the filesystem, so
the update fails with this message (full message in the attachment):
----
/usr/sbin/grub-probe: error: unknown filesystem.
Auto-detection of a filesystem module failed.
Please specify the module with the option `--modules' explicitly.
----
And if I do grub-probe -t fs / manually it returns the same error (unknown
filesystem), downgrading fixes the issue.
The attachment contains all the various combnations of grub-probe outputs under
20100115 (working) and 20100128 (non-working), I've also included both grub.cfg
and menu.lst, a mount(1) output and the full error message returned as output of
"apt-get install grub-pc" on unstable.
Please let me know if you need any other info.
The severity of this "bug" is grave because the package is completely unusable
and there is no way to boot the system unless I downgrade the package.`
Cheers
Antonio
