Replying to LLIyT:

First of all, you should use a recent version of MadWifi for your port. The version you use now has a number of known security issues that have been fixed.

Then you should provide a decoded oops message, as explained on DevDocs/KernelOops. The oops you posted here only mentions "opaque" addresses, making it virtually impossible to tell where and how the oops actually happened.
