Bug#514263: thinks that my ext2 root filesystem is fat

[Joey Hess]

Package: grub-pc
Version: 1.96+20080724-14
Severity: normal

When I chainload into grub 2 from grub, it fails to show a menu,
I think it said file not found.

If I type root or root (hd0,1), it says "FAT filesystem",
and ls fails to show any files.

This laptop is a dell mini 9, the only disk is a SSD, which
is partitioned as follows:

Command (m for help): p

Disk /dev/hda: 30.8 GB, 30816608256 bytes
255 heads, 63 sectors/track, 3746 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x010fc343

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1        3746    30089713+  83  Linux

The filesystem is formatted ext2.

root at gnu:/home/joey>file -s /dev/hda1
/dev/hda1: Linux rev 1.0 ext2 filesystem data (mounted or unclean), UUID=76063b7a-7534-4a51-92d9-62b685cf4d48, volume name "gnu-root"

I don't know why it says this is FAT.. 

Grub 1 boots fine.
