I have an Asus K73TA laptop with AMD A6-3400M APU and Radeon 6550 GPU. I get foloowing errors on boot with Kernels version 3.13 and above: [ 53.720848] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 53.720975] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CE56 (len 62, WS 0, PS 0) @ 0xCE72 [ 53.721107] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BB62 (len 1036, WS 4, PS 0) @ 0xBC5F [ 53.721240] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BAF8 (len 76, WS 0, PS 8) @ 0xBB00 [ 55.775951] [drm:r600_ring_test] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xFFFFFFFF) [ 55.776083] [drm:evergreen_resume] *ERROR* evergreen startup failed on resume [ 55.776364] [drm:radeon_pm_resume_dpm] *ERROR* radeon: dpm resume failed Initially I thought this is Debian specific so I reported it on Debian BTS, it has more details here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737684 I bisected kernel versions between 3.12 and 3.13 and I determined that this issue was introduced in the following git commit: commit 10ebc0bc09344ab6310309169efc73dfe6c23d72 Author: Dave Airlie <airlied@xxxxxxxxxx> Date: Mon Sep 17 14:40:31 2012 +1000 drm/radeon: add runtime PM support (v2) This hooks radeon up to the runtime PM system to enable dynamic power management for secondary GPUs in switchable and powerxpress laptops. v2: agd5f: clean up, add module parameter Signed-off-by: Dave Airlie <airlied@xxxxxxxxxx> Signed-off-by: Alex Deucher <alexander.deucher@xxxxxxx> Newgarry, can you please try kernel v3.12 and see if it works correctly for you? Because of this issue I cannot upgrade my kernel to anything above 3.12. I spent a week bisecting the kernel, so I would really appreciate someone looking into this. I tried reviewing the changes introduced in this commit, but I know too little about radon drivers to be able to understand the impact they had. If you need me to do any additional testing or provide you with extra information, please don't hesitate to contact me, I'll do what I can.
