[asterisk-users] Bristuff qozap drivers problem

[Steve Davies]

Hi,

For a significant time now (since about 0.2.0-rc8n) the qozap driver
has become very verbose if an ISDN line is not connected... I get the
messages below every couple of seconds in the asterisk logs.

The "flaw" in the messages is the "Alarm cleared" message - The alarm
cannot possibly be cleared because there is no physical media
connected into that port!!! (BTW - All ports are in TE mode.)

Can anyone suggest a cleanup in qozap.c that will prevent it telling
Asterisk that the channel is up unless it actually has come back up? I
do not understand the zaptel/bristuff internals well enough to be able
to find where this is occuring.

I also get a solid kernel crash with no Oops if I unload the qozap
module - Again this does not happen in the older versions of the qozap
module. I am using Kernel 2.6.10.

Many thanks for any pointers,
Steve.
