Retrying it...
Seems like it is _not_ reproduceable currently!
The mkreiserfs ran through it without any problems!
If I can reproduce it again, I will send all
informations.

Mount and delete.

reiserfs

I created 200000 empty files, and then deleted them.

ext2: creating took a very long time, I aborted (was about 7 minutes)
reiserfs: creating was done in about 3 minutes

ext2: deleting started with find | xargs rm, no problem.

reiserfs: started deleting, recieved NULL pointer
(kernel oops)

It's been the same disk.
and i don't think it was a reply, because I created the
filesystem some seconds before.

Hmm.... I used udma33 :(

You are right. I was only surprised that the so called
fast reiserfs takes soo long at mounting.

It was impossible to delete the files on the one partition.
(see above) The problem is, after I reformated the partition
it was not reproduceable.

It seems there are some strange things in reiserfs, which
happen at special situations.
