Created attachment 255925 [details] dmesg I had a Dell Notebook Inspiron 5548, and since I bought it, I can't run the amd drive property. I upgrade my kernel to 4.9 version, and even I upgrade, the problem still the same. In attach I send the dmesg, lsci and lshw. If anyone can help me, I would be very grateful Linux 4.9.0-2-amd64 #1 SMP Debian 4.9.18-1 (2017-03-30) x86_64 GNU/Linux

What exactly is the problem? The only suspicious thing in dmesg is the below, which indicates that the GPU's power management might not be working perfectly: [ 20.346154] cant't get the mac of 5 [ 20.348337] [ powerplay ] VBIOS did not find boot engine clock value in dependency table. Using Memory DPM level 0!

Using Memory DPM level 0! hello, there is the same problem in my dell Inspirion 5547. my output of `dmesg --levle=err,warn ` like this: > [ 5175.824105] amdgpu: [powerplay] VI should always have 2 performance levels > [ 5181.060603] amdgpu: [powerplay] can't get the mac of 5 > [ 5181.061744] amdgpu: [powerplay] VBIOS did not find boot engine clock value > > in dependency table. Using Memory DPM level 0! > [ 5186.704831] amdgpu: [powerplay] VI should always have 2 performance levels > [ 5191.861423] amdgpu: [powerplay] can't get the mac of 5 > [ 5191.862585] amdgpu: [powerplay] VBIOS did not find boot engine clock value > in dependency table. Using Memory DPM level 0! > [ 5196.872216] amdgpu: [powerplay] VI should always have 2 performance levels and my previous kernel version is 4.10-11-1-ARCH, now, I changed my kernel to 4.11.0-rc8-g5a7ad1146caa. however, the bug isn't solved. And I also checked the kernel code of drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c, this file's bug has been fixed since the bug#185681. however, my kernel also has the error of powerplay. so annoying. can you have any suggestion for me to solve this problem? Thanks grateful!
