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 :)
