Summary:                    deadlock using hardware transcoding card
Description: 
At a random pace (once or twice per day on the average), two asterisks of
ours seems caught in a deadlock. The CLI stop working on some command
("core show channels" for example, while "sip show channels" keeps working
well). Moreover, asterisk stop responding on the SIP UDP port, and I cannot
restart asterisk, having to reboot the machine.

Sometimes on one of the two, the kernel completely hangs, and a manual
reset must be performed.

Sorry, I didn't mentioned it, but we are using as transcoding card the
digium TC400B, either in g729 mode, or in mixed mode.

Also the deadlocks seems not related to the server call loads,
notwithstanding having a soft preference over peak hours. Anyway at peak we
have 60/90 channels, whose only less than a half are effectively transcoded
with the card.
