Choose appropriate function from stack which has failed. Suppose
function failed is "function_foo()" then you will have entry like
kernel: [<ffffffff814ec2ba>] ? function_foo+198
in stack trace. Pass corresponding debug .ko to gdb and give command
(gdb) l* function_foo+198
This will give you .c file which caused failure with line number.
Suppose you got details like .c file is foo.c and line number is 122
then you can do more debugging with following command
(gdb) info line foo.c:122
BTW can you put stack trace (if you are allowed) on thread ?
