Do you have any way to reproduce?

So it's died here:
  /* for each real block, add it to the journal list hash,
  ** copy into real block index array in the commit or desc block
  */
  for (i = 0, cn = SB_JOURNAL(p_s_sb)->j_first ; cn ; cn = cn->next, i++) {
    if (test_bit(BH_JDirty, &cn->bh->b_state) ) {

(in test_bit) because cn->bh is zero.
Hm. Chris, do you have any ideas how that might have happened?

Bye,
