I think I have the same (or highly similar) thing happening on ia64. 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 <a0000001003d6690> 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)
