[Click] Howto find the elemet that generete the kernel oops?

[Torquato Bertani]

Hi,
I have a kernel oops like the one at the end of email, how can I find
which click element generate it? I'm running click as kernel module.
In my oops I can't see the name of functions called but only memory
positions, why? I read some posts and all kernel oops reported have
the name of the function in the Call Trace.
I don't have much experience in linux kernel modules debugging, maybe
this is the problem :)
Thanks
Torquato
