has anyone seen similar behavior?

while in a loop running runalltests.sh from LTP (ltp-full-20040804) as
regression test on ia64 I get the following crashes:

kernel 2.6.7 (see attached detailed log)
-------
The kjournald daemon hits a bugcheck:
    Assertion failure in journal_commit_transaction() at fs/jbd/commit.c:760: 
"jh->b_next_transaction == ((void *)0)"
kernel BUG at fs/jbd/commit.c:760!
having a look with kdb, we see a process running at same time in 
journal_dirty_metadata():

kernel 2.6.9-rc2 (see attached detailed log)
----------
kjournald gets an invalid address in __journal_file_buffer() called from 
journal_commit_transaction(). Several processes are
waiting for locks in jbd. struct journal_head  looks corrupted.
