Summary:                    Loading and Configuring wctdm breaks various system
commands
Description: 
Im using asterisk-rc6 with dahdi rc5 (or rc4, does not matter). After
loading the wctdm module and configuring the channels with dahdi_cfg varios
system commands do stop working. For example, the ssh server responds
unpredictable (existing connections close). Also ssh-keygen seems to hang
in a loop.
If remove the channels from system_conf, execute dahdi_cfg and unload the
module ssh works fine again.
I cannot break it down to any special revision, but the last zaptel
revision worked.

I have done this, I also disabled "alawoverride" and "alaw=1-4", so
everything is working with ulaw, dahdi is 2.0.0, asterisk is 1.6.0 Same
symptons, system is unstable, ssh not possible, asterisk crashes 4 of 5
times when starting. After disabling dahdi/wctdm ssh works again. FYI,
nothing is plugged into the card.
