Can you try disabling additional dpm features as per previoous comments? e.g, diff --git a/drivers/gpu/drm/radeon/rv6xx_dpm.c b/drivers/gpu/drm/radeon/rv6xx_dpm.c index bdd888b..ad17ae8 100644 --- a/drivers/gpu/drm/radeon/rv6xx_dpm.c +++ b/drivers/gpu/drm/radeon/rv6xx_dpm.c @@ -1982,10 +1982,10 @@ int rv6xx_dpm_init(struct radeon_device *rdev) else pi->fb_div_scale = 0; - pi->voltage_control = - radeon_atom_is_voltage_gpio(rdev, SET_VOLTAGE_TYPE_ASIC_VDDC, 0); + pi->voltage_control = false; +// radeon_atom_is_voltage_gpio(rdev, SET_VOLTAGE_TYPE_ASIC_VDDC, 0); - pi->gfx_clock_gating = true; + pi->gfx_clock_gating = false; pi->sclk_ss = radeon_atombios_get_asic_ss_info(rdev, &ss, ASIC_INTERNAL_ENGINE_SS, 0); @@ -1994,13 +1994,14 @@ int rv6xx_dpm_init(struct radeon_device *rdev) /* Disable sclk ss, causes hangs on a lot of systems */ pi->sclk_ss = false; + pi->mclk_ss = false; if (pi->sclk_ss || pi->mclk_ss) pi->dynamic_ss = true; else pi->dynamic_ss = false; - pi->dynamic_pcie_gen2 = true; + pi->dynamic_pcie_gen2 = false; if (pi->gfx_clock_gating && (rdev->pm.int_thermal_type != THERMAL_TYPE_NONE)) See if disabling any additional features helps stability on your system. > > ps.: I'm not too lucky with this DPM thing. The old card dies randomly > (WSOD), and the new one is not supported (SI). SI cards are supported just fine, including dpm.
