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)

Severity: major

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
