journalctl: amdgpu lockup on resume from sleep.

My system locks up when trying to wake from sleep (open lid).  The screen
remains black and is unresponsive to keyboard/mouse input.  I'm able to ssh
from another machine and have attached the output from journalctl -b.  The log
shows scrolling errors...

kernel: [drm:amdgpu_job_run [amdgpu]] *ERROR* Error scheduling IBs (-22)
kernel: amdgpu 0000:05:00.0: couldn't schedule ib on ring <gfx>

This is a Lenovo E585 laptop with an AMD R5 2500U APU.
