Description

I can have working clear and working HDLCFCS channels on the icE1usb DAHDI driver, but only if I set them correct in the initial configuration. Later reconfiguration renders the channel unusable.

This needs investigation

ok, so the way I reconfigure the channel is by changing /etc/dahdi/system.conf and then calling dahdi_cfg. This doesn't only change the channel config, but also setst the span config. And it is exactly where I suspect the bug is. Our implementation of e1u_d_spanconfig() calls e1u_d_startup() without e1u_d_shutdown().
