--- Comment #8 from Adrien Prost-Boucle adrien.prost-boucle@laposte.net --- Hi,
I also experience this problem with my laptop at resume from sleep.
About log messages, there does not seem to be a message when entering sleep. When resuming from sleep, I can briefly see this message printed on the screen:
kernel: [drm:rv730_stop_dpm [radeon]] *ERROR* Could not force DPM to low
However at boot time, I see this in the log:
kernel: [drm] initializing kernel modesetting (RV710 0x1002:0x9553 0x1179:0xFF00).
I see a switch from rv710 to rv730, is this normal? Previously, Thaddäus Tintenfisch reported a switch from rv730 to rv770...
If useful, the lspci command says:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV710/M92 [Mobility Radeon HD 4530/4570/545v] 01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] RV710/730 HDMI Audio [Radeon HD 4000 series]
The patch proposed just before seems to be explicitely related to rv770, which does not seem to be my case.
