Similarities: seeing assertions fail for b_transaction Differences: I only have ext3 filesystems mounted, no ext4 See attached trace. I'm pretty certain that the highly unhelpful bugcheck! 0 [1] comes from the J_ASSERT_JH(jh, jh->b_transaction == NULL); from disassembling __journal_remove_journal_head(). The instruction pointer points to the 2nd "break" instruction in the function. The problem shows up after 30 minutes to a couple of hours of stress (kernel builds with "make -j32"). I'm pretty sure this problem didn't occur in plain v3.9 (it can run for a full 24 hours). Trying to bisect - but it takes a while to be convinced that a good kernel is actually good (since I don't have a clear picture of how long to run before deciding that the bug isn't going to show)
