A decade later, found the same bug in grub.
It might not affect "standard" grub usage (e.g. Ubuntu) where it may not
need to probe and guess filesystem type just to boot the system, but
thank you for the excellent diagnosis nevertheless!

@haskinsa99 Please don't change the status out of Fix Released. That is
the final status for the bug, Confirmed is not a valid state once a bug
has been marked Fixed Released. Thanks.

Kudos to the original reporter and inventor of the ingenious solution. I
was bit by this bug on a regular laptop and dumbfounded as my Lucid
system's "blkid" saw the file system, while the Karmic system didn't.
It would be a very good idea indeed to backport this patch to karmic's
util-linux, as i
Just fixed a 9.10 system using the cure suggested in the bug
description. Will the fix be applied to 9.10 as well?

This script may help identify "at risk" filesystems. For my system, my
/boot partition is vulnerable, but I'd need to create 2 more inodes
to hit the glitch.

This failure mode depends on the size of the filesystem, the number of
reserved blocks, and the inodes used. This series of steps reproduces
the problem for me:
rm -f /dev/shm/test.ext4
dd if=/dev/zero of=/dev/shm/test.ext4 bs=1 count=1 seek=1023M
mkfs.ext4 -F /dev/shm/test.ext4
tune2fs -r 0 /dev
Ah, sorry, I should be comparing against the superblock, not the
group_desc.
uint16_t s_ninodes;
uint16_t s_nzones;
uint32_ts_inodes_count;
uint16_t s_imap_blocks;
uint16_t s_zmap_blocks;
uint32_ts_blocks_count;
uint16_t s_firstdatazone;
uint16_t s_log_zone_size;
Is anyone even using a minix filesystem? I mean can't we just not check
for that?

For a filesystem that fails, can you attach the first 10K of the
partition?
sudo dd if=/dev/sda1 of=/tmp/10k.data bs=10k count=1
The minix sanity checks are failing:
sb = blkid_probe_get_sb(pr, mag, struct minix_super_block);
if (!sb || sb->s_imap_blocks == 0 || s
Hrm, no, I am wrong about location. It does seem to be 0x410, but there
is additional logic in the minix probe that needs to be satisfied. See
probe_minix in shlibs/blkid/src/superblocks/minix.c

I cannot reproduce this with a simple loop-back filesystem:
sudo -s
cd /tmp
dd if=/dev/zero of=test.ext4 bs=1 count=1 seek=1G
mkfs.ext4 -F test.ext4
mkdir -p /mnt/test
mount -o loop text.ext4 /mnt/test
echo $(seq $(hexdump -s 0x410 -n 2 -e '"%d\n"' test.ext4) - 9336 ) | (cd
/mnt/test; xargs touch
