Hi Johannes,

so the initial issue was a BUG_ON when the ucode reports back an
unsupported event. That should have been fixed by now since we just
can't crash the whole kernel, because some piece of firmware acts bogus
now and then. However there seems to be some other issues with me
running a 64-bit OS and connecting to an N-capable access point.

Regards
