It's odd that you're trying to insert the module, which implies
*attaching* to net devices but this trace is
detaching. You'll need to start sprinkling some printks in your code to
identify what is going on. Increase
the logging level with the 'dmesg -n 8' command and provide some extra
context. You may have to hook up
netconsole.
As it is I do not have access to an ARM machine to see if I can
reproduce this. Perhaps someone else
does.
