BUG: Assertion failure with ext3-0.95 for 2.4.7

Hello ext3-users,

I tested ext3 on a Linux for S/390 with several stress and benchmark test
tests and faced a kernel bug message.
The console showed the following output:

Message from syslogd@boeaet34 at Fri Aug 3 11:34:16 2001 ...
boeaet34 kernel: Assertion failure in journal_forget() at
transaction.c:1184: "!
jh->b_committed_data"

I tried the Patch from http://www.zip.com.au/~akpm/ext3-2.4-0.9.5-247.gz
with the kernel 2.4.7 with a new LVM- patch(0.9.1) and some S/390 specific
patches. I use mke2fs version 1.22.
S/390 is a 32bit big endian machine. After compiling and running the kernel
I created an ext3-file system on an 70GB LVM. When running the postmark
test I get (reproduceable) the message from above. dmesg shows:

I resolved the functions using the system.map file.

Has anyone saw this message before? Any ideas, clues, hints?

Please CC me , because I am not on the list.
