I believe this issue has made it onto the show-stopper list for
6.1-RELEASE and is being actively worked on.
It's on the todo list, but I don't think it's being worked on yet.
The main problem is that we need a way to reproduce it on command.
I'd forgotten that snapshots are involved, so maybe it's just a matter
of running lots of mksnap_ffs while I/O is in progress.

It happens with or without snapshots, but snapshots are a lot more likely
to make it happen. In my case, approximately 1 in 3 snapshots will do it.
Without snapshots, I get a deadlock about every ten days in a population
of three hosts.
Tor Egge and Don Lewis were kind enough to work with me off-list for a bit
last December. They analyzed several of the core files I produced and I
think they have a fair understanding of what the problems are. But I
wouldn't presume to put words in their mouths; perhaps they'll give us an
update. I see from the todo list that Tor may already be working on the
deadlock for amd64.
I'm at the disposal of anyone who's willing to look into this further.
