Subject: iwlwifi/iwlmvm dies on resume when rfkill is set
Date: Mon, 1 Jun 2015 15:51:37 -0700	[thread overview]
Message-ID: <CALCETrU+Jk+rNwV7ibCy_LJoHkcgSPr7EFRzCxgSkJ5Jwh5q4w@mail.gmail.com> (raw)

If I switch my laptop into airplane mode (hardware switch) and then
suspend and resume, my wireless is dead on resume and it spews all
over the kernel log (see below).  I can rescue it by switching
airplane mode off and then suspending and resuming again.

This problem has existed on all kernel versions I've tried, although I
haven't tried a 4.0 kernel yet.
