Bug ID: 100759
Summary: [r600] System freeze on resume from sleep on battery
with DPM enabled and linux 4.10
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Radeon
Assignee: dri-devel@lists.freedesktop.org
Reporter: nicolamori@aol.com

journalctl log for failed resume
Since linux 4.10.1 my system freezes every time when resuming from sleep
(suspend to ram) while on battery. The screen either remains black or displays
garbage, and the only thing to do is a hard poweroff. The problem does not show
up when either:
- running on AC or
- using linux 4.9 (tested with 4.9.11) or
- DPM is not enabled (radeon.dpm=0)
I checked journalctl but it does not contain anything useful. I attach the last
part of the log, starting from the suspend request; it seems nothing from the
failed resume process is logged.
System details:
- Archlinux x86_64
- Mobility Radeon HD 3470
- Plasma desktop 5.9.4

I found the time to bisect and found that the culprit is:
commit 1c331f75aa6ccbf64ebcc5a019183e617c9d818a
Author: Lucas Stach <dev@lynxeye.de>

drm/radeon/pm: autoswitch power state when in balanced mode
The current default of always using the performance power state leads
to increased power consumption of mobile devices, which have a dedicated
battery power state. Switch between the performance and battery power
state automatically, dpending on the current AC power status, when the
user asked for the balanced power state.
The user can still override this logic by asking for the performance
or battery power state explicitly.

I don't have the skills to understand what's broken, but I can test an eventual
patch if someone provides it. Thanks.

Hi Alex, any news about the revert patch? Is there any estimate about if and
when it will be mainlined? Thanks.
