Look bad again!
Try to get a backup of the superblock for the file system check.

Here you get the list of superblocks

Code:

sudo gainroot
dumpe2fs /dev/mmcblk0p2 | grep -i superblock

You get an output like this:

Nokia-N900:~# dumpe2fs /dev/mmcblk0p2 | grep -i superblock
dumpe2fs 1.41.3.maemo0 (12-Oct-2008)
Primary superblock at 0, Group descriptors at 1-1
Backup superblock at 32768, Group descriptors at 32769-32769
Backup superblock at 98304, Group descriptors at 98305-98305
Backup superblock at 163840, Group descriptors at 163841-163841
Backup superblock at 229376, Group descriptors at 229377-229377
Backup superblock at 294912, Group descriptors at 294913-294913
Backup superblock at 819200, Group descriptors at 819201-819201
Backup superblock at 884736, Group descriptors at 884737-884737
Backup superblock at 1605632, Group descriptors at 1605633-1605633

Then check the file system with one of the backups again like this

Code:

fsck -b 294912 -af /dev/mmcblk0p2

Hope it helps!
