I have two radeon gpus on my system, see: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Park [Mobility Radeon HD 5430] 06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV635 [Radeon HD 3650/3750/4570/4580] the latter is not used currently. since upgrading to sys-kernel/gentoo-sources-4.2.0 my main gpu hard locks almost every boot. the only way to fix it is to reboot the system. see dmesg of the lock below: Nov 6 19:59:29 NCC-5001-D kernel: radeon 0000:01:00.0: ring 0 stalled for more than 10006msec Nov 6 19:59:29 NCC-5001-D kernel: radeon 0000:01:00.0: GPU lockup (current fence id 0x0000000000001ae7 last fence id 0x0000000000001ae8 on ring 0) Nov 6 19:59:29 NCC-5001-D kernel: [drm:rv770_stop_dpm [radeon]] *ERROR* Could not force DPM to low.

Reproducible: Always
Created attachment 416236 [details] kernel config
Created attachment 416238 [details] emerge --info
Is this still an issue with later kernels?
