Priority: medium Bug ID: 76130 Assignee: dri-devel@lists.freedesktop.org Summary: Radeon HD 4570 set dpm state fails after suspend Severity: normal Classification: Unclassified OS: Linux (All) Reporter: crew4ok@gmail.com Hardware: x86 (IA32) Status: NEW Version: unspecified Component: DRM/Radeon Product: DRI
Created attachment 95731 --> https://bugs.freedesktop.org/attachment.cgi?id=95731&action=edit 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).
