Ah ... I missed this one ... but good to know that it is a bug ... my first
step/workaround was to set the noauto option in fstab.
Now I have to find a way to bring the system to umount my ext2fs partition
(it is not only because of the syncing discs error but also my debian box
will run later on after rebooting the fsck check for about 10 minutes :-( ).
I was trying to bring the kernel automounter amd to mount the debian
partition but still did not succeed.
My second idea was to run a chron-job to umount my partition every 2 minutes
or so ... or set an alias on shutdown (with something like alias shutdown
umount /mnt/debian , shutdown -p now) ... I still do not know.

... don't touch the bang bang fruit
