dmesg
Right before the system go to suspend, the following line appears in dmesg:
[drm:rv730_stop_dpm] *ERROR* Could not force DPM to low
After wakeup i see this in dmesg:
[drm:rv770_dpm_set_power_state] *ERROR* rv770_set_sw_state failed
Also i notice a degradation in performance in some games (e.g. in Teeworlds
before the suspend i have 60fps, after suspend - 30-40 fps).
