Yes, a common problem.

You are using SuSE with 2.4.10 kernel?  It is broken when creating a
journal on a mounted filesystem.

To remove the existing journal "chattr -i /.journal; rm /.journal".
To create a new journal you either need to boot to another kernel
version, or boot from a CD or floppy, and "tune2fs -j /dev/hda3".
