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 sruffell,

There is no "Use 4Kb for kernel stacks instead of 8Kb" kernel hacking
option for 2.6.24 in Fedora 8 kernel (fedora pacthed and vanilla kernel).
The only stack options are "Check for stack overflows" and "Stack
utilization instrumentation".

Does it needs any pacth? Where I can get it?

Regards
