SubjectD state processes in 2.4.18-pre7-ac3
Linux incandescent 2.4.18-pre7-ac3 #1 Tue Feb 5 01:00:50 EST 2002 i686 unknown

I came home today to a bunch of processes apparently hung in jbd's
do_get_write_access(); apparently, something deadlocked, where no
processes could write to one of my partition's journal. That's my
theory, anyways. Several processes had stacks similar to:

Call Trace: [<c011271d>] [<d08ecac7>] [<d08ecd08>] [<d08fb892>]
[<d08ec262>]

And, kjournald had the following:

Call Trace: [<c0131f0a>] [<d08ee6e6>] [<c0112380>] [<d08f08eb>]
[<d08f07c0>]
[<c010f4e8>]
Warning (Oops_read): Code line not seen, dumping what data is available

Trace; d08f07c0 <[jbd]commit_timeout+0/10>
Trace; c010f4e8 <mtrr_read+68/80>

Not sure what caused the actual deadlock; the partition uses lvm and
ext3, and the underlying controller uses hedrick's pdc driver.

be causing this, or what to look for the next time this happens..
