Summary:                    random panics on disconnects
Description: 
Lately with our internal copy of dahdi trunk we started getting occasional
panics on disconnects.

This started only after merging post-2.2 changes. My suspect so far is
r6794 (the drivers reference counting) but I haven't had the time to trace
this issue yet.

Scenario: 

1. disconnecting a device
2. Sending Asterisk a "remove" event
3. Asterisk closes the file descriptor
4. Panic

This seems to have been resolved in r7066 , which fixes a regression added
in r6794 : Don't dereference the span after a channel was closed.
