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

[Torquato Bertani]

After many tests (I eliminated one element at a time...) I found the
element that seems to generate the oops: ARPQuerier. I updated my
arpquerier source code (I was working on a dated version) and the
problem seems to be resolved.

I still would like to know how to debug click in kernel mode if anyone
else know...

Thanks!
Torquato
