Hello,

 

While performing a rmmod on a WiFi device driver, I'm seeing a crash in the kernel. Backtrace is as follows:

 

Program received signal SIGSEGV, Segmentation fault.

There isn't anything dumped to the console, this backtrace was retreived using GDB. We're currently using 2010R1 release of the uCLinux distrobution. What can I do next to debug this issue?
