<pre>I started seeing this ~4.4rc7 (might have been on rc6 but i don't think so...
for sure it was there in rc8).
I am on kubuntu 15.10 on Intel i5-3317U, using ubuntu kernel-mainline 4.4
Its not clear that suspend/resume is involved. It will happen while using it
w/o a resume, but may happen on each resume too(?)
its relatively frequent, ~1-2 times / hr.
