My suggestion would be to run this:

  fsck -b 16384 -a -f /dev/hda2
  sync
  reboot

If your filesystem has errors that fsck can't fix automatically,
There's probably not much else you can do but re-install.  It's
theoretically possible to recover a filesystem by fixing it manually,
but I don't know anyone who can actually do this.  At that point,
mount your fs and get whatever data you can recover from it, and
re-install.
