4.14.0-rc3 iwlwifi: Hardware became unavailable during restart

From: Seraphime Kirkovski
Date: Tue Oct 10 2017 - 03:44:24 EST

Hello,

I've got this splat after a couple of suspend-resume cycles on my
HP-laptop. I haven't had the time to bisect or test other rcs for now.
Pasting some logs before the actual WARN_ON, as they may be relevant.
Just after the splat the connection is successfully reestablished.
