>Description:
Crashes associated with the ZapTel driver are occuring for some users, the machine will just lock up when either shutting asterisk or testing the zaptel interface details can be found here http://lists.digium.com/pipermail/asterisk-bsd/2005-February/000568.html and in other messages in that list.
>How-To-Repeat:
It only occurs on some machines, I have accesses to 3 machines running the same versions and config files and it only happens on one of them, other people have reported similar problems and similar lack of problems to the list,  zaptel cards in the three machine are identical.
>Fix:
Update the file /usr/ports/misc/zaptel/files/patch-zaptel::zaptel.c to include the following as documented in the above E:mail to the mailing list.
