Summary: [Pyro] Internal display brightness is '0' after Suspend/Resume the device (was: [Pyro] Internal display brightness is '0' after Suspend/Resume the device with external monitor connected)
Tested with today's ToT 9715.0.0, 61.0.3147.0 and observed that the issue is seen by suspend/resuming the device itself, not just connected to external monitor.  Updated the description and title.

A ping as we're working to eliminate the list of M61 Beta blockers.   This one is a bit stale.  Thanks bunches...

Ping since we're planning a Beta release next week.  Can we escalate since this is tagged as a beta blocker?  IMing marcheu@ as well; thanks :-)

Someone on the graphics side needs to take a look. powerd.LATEST suggests that the brightness is being restored, at least from userspace's perspective (and that code hasn't changed in forever):

Stéphane Marchesin called out that this is being fixed by Intel (per my IM); need to monitor / test / unblock. 
Hi all, we're targeting a Beta next week so we need fixes and/or workarounds submitted by COB Monday 8/14 if this is still considered a beta blocker.  Possible?     Thanks!
I am not able to reproduce the issue in Chrome OS 9765.29.0, 61.0.3163.47. 
marcheu@ based on comment 13, do we think this issue might have been resolved?

Why duped to Candy(after recovery) issue?

This is different from candy's issue

Actually no, it's the same thing as well; so we're all good.
