Summary:                    Cannot unload wct4xxp zaptel kernel module
Description: 
I cannot unload a unused wct4xxp zaptel kernel module. Every time I try to
remove it I get a kernel oops/crash.

1. boot-up the system
2. load zaptel module (modprobe zaptel)
3. load wct4xxp module (modprobe wct4xxp)
4. unload wct4xxp module (rmmod wct4xxp) <<--- it says that it's in use
and crash!
5. unload zaptel module (rmmod zaptel)   <<--- I can't get here since 4
failed

Hi fhidalgo,

In all systems that I tested, I cannot unload the wct4xxp module. It not
board dependant... If I have no boards in the test machine and try to
unload it, I get the kernel oops.

Did you realy can unload the wct4xxp kernel module? Can you make it clean
to us?

Thank's
