If i'm not wrong I think I have had something around the same place "ext3 
journalling":

1)
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! (fs/jbd/transaction.c, 954): 
journal_dirty_data: jh: e0000023ee0f9a58, tid:205049

2)

reading your email I decide to start a test and get this:
(fs/jbd/transaction.c, 954): journal_dirty_data: jh: e0000023ee0f9a58, tid:205049
kernel BUG at kernel/timer.c:416!
mkdir09[30886]: bugcheck! 0 [2]
/* Linux version 2.6.10 with CONFIG_JBD_DEBUG enable */


hope that it can help,

Jacky
