kernel panics and warnings #35

Closed furlongm closed 8 years ago

Hi,

Getting consistent kernel panics and warnings with the builtin driver on kernel 4.2.0-1.gefc468a-desktop. I haven't captured the panics yet, but the output from the warning is below.

Trying to build the out-of-tree module also fails on 4.2 so I currently need to fallback to the out of tree module on 4.1.

I've changed the code to: hw->flags[0] =

The code had compiled successful, but I cant connect to AP. Could you try on your hardware?

Fixed in mainline kernel.
