Assertion failure in journal_commit_transaction() at fs/jbd/commit.c:496:"commit_transaction->t_nr_buffers <=commit_transaction->t_outstanding_credits"

[Justin Piszcz]

Hi,

I have the same errors as these folks:
https://bugzilla.redhat.com/show_bug.cgi?id=563247

OS: RHEL 5 x86_64
Kernel: 2.6.18

I see this on a wide variety of hardware and according to the bug report,
it happens whether its hardware raid or dm.

Since there are no records of this bug/issue on LKML I thought I'd pose the
question.  I am just looking into what is the root cause here, is it an ext3
bug?
