Hi!

Here's problem bisected down to:

commit 9d659ae14b545c4296e812c70493bfdc999b5c1c

    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?

If I put laptop to suspend or hibernate by closing lid, power
manager or any other method and then I resume/wake up laptop, keyboard
is not responding. My laptop is a Sony Vaio VPCEH2F1E. 

Steps to produce bug:
1. Boot
2. Put laptop to sleep
3. Resume

What I expect to happen: Keyboard responds to key press.
What happens: Keyboard does not respond but mouse and trackball are
working.
