Sean Bright commented on DAHLIN-268:
------------------------------------

We unload and reload the driver each night, so this will help us get through the day.  I will roll it out tonight.

> seanbright reported on IRC that the wctc4xxp driver can sometimes report:
> {noformat}
> [3133994.496258] wctc4xxp 0000:07:08.0: Failed to create channel in timeslot 52.  Response from DTE was (ffbd).
> {noformat}
> When this happens, the card typically has that channel stuck and will return an error message on any new channel creation until the driver is reloaded. While unclear how the firmware gets into this state the driver could be more proactive about minimizing the impact of this on a running system by marking channels as in use and not trying them until after a reload, and optionally reloading after the channel use count is at 0 for some specific amount of time.
