After looking at this core show locks and backtrace I see two things:

The devicestate code is doing a DNS lookup on the name of a peer. This
should only happen if the peer doesn't exist and it should also not take
that long. Is your configuration proper with that peer configured and is
your server setup with working/reliable nameservers?

Secondly the scheduler looks to be rescheduling things, which is perfectly
normal and should not cause a deadlock.

What exactly did you experience that made you consider this a deadlock?
What couldn't you do? What were you doing? What sort of call capacity does
the machine run? How many configured entries in sip.conf?
