bcm43xx causes kernel oops on 4318 with latest wireless-dev git.

Jory

That's hardly readable.
But which firmware are you running? v4.x by chance?

Greetings Michael.

No that is version 3.x.

4.x firmware won't work. Make sure to use 3.x.

I am not sure what happens.
Any chance to get a more complete oops message? I am also interrested in the start of the oops message. In particular I would like to see if this is a NULL pointer bug, machine check or something else.
The backtrace is a little big weird. So I am not sure what happens.

And, Please make _really_ sure to use 3.x firmware. ;)

Greetings Michael.

alright here are two more pics for you.
