4.11-rc* iwlwifi instable

[Andi Kleen <andi@firstfloor.org>]

Hi,

Since I updated my laptop to 4.11-rc* the wireless is fairly instable
(I think it was already less stable with 4.10 than with 4.8, but no
clear data) 

For example it locked up (no more wireless) with a warn on while connecting
and actually needed a reboot to recover (reloading modules was not
enough)

Any fixes/workarounds?

Thanks,
-Andi
