I probably should mention that I have not tested to change 'power_dpm_force_performance_level' or 'power_dpm_state', so both of them are at their default. 1) with radeon.dpm=1 the GPU will not be initialised correctly due to some issues with the UVD, here the log: [drm:uvd_v1_0_start [radeon]] *ERROR* UVD not responding, trying to reset the VCPU!!! [drm:uvd_v1_0_start [radeon]] *ERROR* UVD not responding, giving up!!! [drm:r600_startup [radeon]] *ERROR* radeon: failed initializing UVD (-1). radeon 0000:01:00.0: ring 0 stalled for more than 10020msec radeon 0000:01:00.0: GPU lockup (current fence id 0x0000000000000000 last fence id 0x0000000000000001 on ring 0) [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait failed (-35). [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-35). [drm:radeon_device_init [radeon]] *ERROR* ib ring test failed (-35). 2) with radeon.dpm=1 and radeon.hard_reset=1 the GPU will be initialised correctly and the system will bootup properly. However, when opening google-chrome the GPU will lockup and the X-server crashes, here the log: radeon 0000:01:00.0: ring 0 stalled for more than 10465msec radeon 0000:01:00.0: GPU lockup (current fence id 0x0000000000009ca0 last fence id 0x0000000000009cc3 on ring 0) radeon 0000:01:00.0: Saved 1113 dwords of commands on ring 0. radeon 0000:01:00.0: GPU softreset: 0x00000008 radeon 0000:01:00.0: R_008010_GRBM_STATUS = 0xA0003030 radeon 0000:01:00.0: R_008014_GRBM_STATUS2 = 0x00000003 radeon 0000:01:00.0: R_000E50_SRBM_STATUS = 0x200000C0 radeon 0000:01:00.0: R_008674_CP_STALLED_STAT1 = 0x00000000 radeon 0000:01:00.0: R_008678_CP_STALLED_STAT2 = 0x00000000 radeon 0000:01:00.0: R_00867C_CP_BUSY_STAT = 0x00020186 radeon 0000:01:00.0: R_008680_CP_STAT = 0x80028645 radeon 0000:01:00.0: R_00D034_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: R_008020_GRBM_SOFT_RESET=0x00004001 radeon 0000:01:00.0: SRBM_SOFT_RESET=0x00000100 radeon 0000:01:00.0: R_008010_GRBM_STATUS = 0xA0003030 radeon 0000:01:00.0: R_008014_GRBM_STATUS2 = 0x00000003 radeon 0000:01:00.0: R_000E50_SRBM_STATUS = 0x200080C0 radeon 0000:01:00.0: R_008674_CP_STALLED_STAT1 = 0x00000000 radeon 0000:01:00.0: R_008678_CP_STALLED_STAT2 = 0x00000000 radeon 0000:01:00.0: R_00867C_CP_BUSY_STAT = 0x00000000 radeon 0000:01:00.0: R_008680_CP_STAT = 0x80100000 radeon 0000:01:00.0: R_00D034_DMA_STATUS_REG = 0x44C83D57 radeon 0000:01:00.0: GPU pci config reset radeon 0000:01:00.0: GPU reset succeeded, trying to resume [drm:radeon_pm_resume [radeon]] *ERROR* radeon: dpm resume failed radeon 0000:01:00.0: Wait for MC idle timedout ! radeon 0000:01:00.0: Wait for MC idle timedout !

I hope this helps to track down and fix this issue. If there is something I can test or help otherwise, please let me know.
