OK, I tried it now  with md  and the bug was there again. Now during a rm
-rf * .
As the bug ouccured with LVM __and__  with MD it looks like a ext3-problem.
Tom Rini reported the same problem on a PPC-Box. Possibly it is a big
endian problem.

The message was again:
kernel: Assertion failure in journal_forget() at transaction.c:1184:
"!jh->b_committed_data"


Here a have a new backtrace, I resolved the functions manually from
system.map -hopefully without a mistake.
