[Asterisk-Dev] wctdm driver broken?

[Fernando Romo]

Steve:

When try to unload the zaptel modules with the last CVS head, the 
drivers has a lock with the digium cards (in my case a TDM400 and E100P) 
and send the messagge: "FATAL: Module zaptel is in use".

Obviusly i stop Asterisk and then go to unload the zaptel drivers. this 
happen one week ago after update the cvs versions of zaptel. I don't 
trace deeple beacouse the error was in a test machine and only see when 
reboot or try a manual unload.

The same behaivor appear when i left "kudzu" active, i notice this kind 
of "hardware searchers" block the PCI Channel of Digium cards, I think 
something are missing in the tdm drivers.

You try with older versions of zaptel drivers?

Regards..... Fernando Romo
