[bug #60565] GRUB 2.06-rc1 doesn't detect a FAT filesystem

[Pawel Veselov]

Follow-up Comment #3, bug #60565 (project grub):

I ran into this today. The EFI file system itself wasn't readable. The reason
was some corruption, fsck created a bunch of FSCKxxx.REC files with zero
timestamps. This made this check fail:

fat.c

      if (info.mtimeset == 0)
        grub_error (GRUB_ERR_OUT_OF_RANGE,
                    "invalid modification timestamp for %s", path);


Deleting the files "fixed" this, and I didn't dig any further. I think the
code checks the timestamp on /, so maybe that was corrupted, and deleting
files just updated the timestamp. I  didn't have enough patience trying to
reproduce this by meddling with timestamps.
