Hi Bastien,
This really looks like a hung task detector report.
Several tasks are stuck in queue_log_writer(), waiting
to be woken up on the "journal->j_join_wait" event and
that never happens because the waker is also stuck.
The problem is your report doesn't show where the waker
is stuck, but the hung task detector reports it, it just
did before or after the chunk you've posted.
If you could provide me the entire report, I could fix this
easily.
There are three places that can do this wakeup:
- reiserfs_allow_writes()
- wake_queued_writers()
- do_journal_end()
So it would be really great if you could select the following
config options:
CONFIG_REISERFS_CHECK
CONFIG_PROVE_LOCKING
CONFIG_DEBUG_SPINLOCK_SLEEP
CONFIG_DEBUG_MUTEXES
CONFIG_DEBUG_SPINLOCK
CONFIG_FRAME_POINTER
CONFIG_DETECT_HUNG_TASK
and try to reproduce the problem. You need to wait 3 minutes after
the lockup. And then, dmesg must contain everything I need to
fix this.
Thanks a lot in advance!

Unfortunatly it was the only trace I could get, will try to reproduce it however.

I have manged to reproduce it after six hour of stress. Unfornatly locked was
disabled due to a known non bug, in the init sequence. I have used sysrq -t in
order to get more information to you.
Do I need to try to reproduce it, with a newer kernel ? Or it is sufficient ?

Without debugging enable lock up take about 30 minutes to occurs but
are really hard to reproduce with debugging on

Ok, this time I don't have the feeling that a deadlock between reiserfs lock and
another lock is involved.
We entered queue_log_writer() and then waited for someone to call do_journal_end()
to testify he finished his job with the journal.
But somehow that didn't happen. Or may be we called queue_log_writer() but we shouldn't,
thinking there was a writer already but there wasn't. Or there is a crazy race somewhere.
On which kernel do you see this? Do you know a kernel on which you've never seen it.
Were you running something specific to trigger this deadlock?
Thanks!

Nothing specific but it is trigger by kmail reading my mail each time...

How do you know you reproduced it? You had a crash before using SysRq?
Or you felt a deadlock or so?
What's interesting is that report is that there is no blocked task
that holds the reiserfs lock.
So I really feel the problem is that someone opened the journal but did not
release it.
How hard is it to reproduce now? If it's not so hard or haphazard, we should
start a bisection. Otherwise I think we'll need to do some tracing and this
is going to take several tries :)

Could you add a virtual lock for testing this hypothesis ? This lock
will be held during journal opening and releasing during journal
closing, using lockdep for testing this hypothesis ?

That's a good idea. But we can get the same result with traces more easily.
Plus I would like one more level of details about the origin of the issue.
We shouldn't skimp on dumping informations, given how hard it is to
reproduce ;)
So here is a patch that inserts some debug tracing points in the journal
opening and journal closing points, so that we can find if there is any
imbalance here, namely to find if the problem is some path that forgets
to close the journal (calling do_journal_end()).
But the reason could be something else. Like for some reasons writers
queue themselves waiting when they shouldn't.
So I've inserted two more points that will let us know why the hung tasks
have put themselves in queue.
This all should narrow down the possible origins of the issue.
You will need to select CONFIG_TRACING. Just select
Kernel Hacking
Tracers
[*] Trace process context switches and events
Or whatever option inside Tracers menu.
And when your problem triggers, type the sysrq combination
to dump ftrace buffers: Sysrq z
Ah and also boot with the ftrace=nop parameter, this will give you
enough size for the buffer, although I guess the default size should
be enough but we never know.
Thanks.
