Subject[regression, bisected] Keyboard not responding after resuming from suspend/hibernate
Hi!

Here's problem bisected down to:

commit 9d659ae14b545c4296e812c70493bfdc999b5c1c
Author: Peter Zijlstra <peterz@infradead.org>
Date: Tue Aug 23 14:40:16 2016 +0200

locking/mutex: Add lock handoff to avoid starvation

Implement lock handoff to avoid lock starvation.

Numan, I assume revert of that patch on the 4.18 kernel still makes it
work?

Peter, any ideas?

Pavel
