now, this used seriously more memory, and cpu,
and the box went thrashing.
after some experimenting,

xfs_repair -o bhash=512 

got it going without using excessive amounts of swap,
so it finally finished after about 12 hours
(2.6.20 needed 8:30, repeatable).

it did not change the situation, however.

I know I could clean these using xfs_db and an additional run of
xfs_repair, but I'm going to keep these around for some more time, in
case you want me to have a look at some internals still.

file system itself has gone life again, I hope it does not hurt having
those strange directories around.

maybe it is even "just" a problem on the kernel side,
not being able to convert so the expected "form" of directory?
sorry, I'm not too deep in the xfs internals, so I need some input from
the developers here...
