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

Hmm....if you can recompile your kernel and make sure the option "Use 4Kb
for kernel stacks instead of 8Kb" under Kernel Hacking is disabled, and
then rebuild your kernel.  Also, you may be able to contact Digium
technical support for more specific help with this issue if you require
help rebuilding / reinstalling your kernel.
