I had some problems with my Asterisk installation having the PRI
channels lock up completely when certain types of calls were
received. Eventually this was traced back to a deadlock caused by the
bristuff patches being applied.
Various information, logs and a stack trace of the lockup here:

I'm choosing severity "grave" because this effectively will allow
someone calling in with particlar caller ID options/flags to lock up
your PRI span on demand (i.e. DoS).
Well, this is definitely a very nasty bug but from a release prespective
I'd like to point out two things:
a) You are one of the _very_ few people to experience this deadlock;
I've experienced it once or twice in one of my (many!) installations
all this time and noone else has reported it so far. Perhaps it has
something to do with what the network sends to Asterisk, I'm not so
sure myself.
b) Asterisk is a very complicated program with dozens of threads and
locks between them. I don't think we (as in, Debian) can solve this
and I highly doubt that upstream will, at least in time for lenny.
In summary, while I acknowledge that this breaks your setup -and believe
me, I'd like to have this fixed as much as you do- I don't think it's a
release critical bug and that it should prevent Asterisk from being
shipped with our next stable release.
Thanks,
Faidon
