--- Comment #21 from MasterCATZ (mastercatz at hotmail.com) ---
Having simular issues with 5.3.8-050308-generic 

when it starts happening this is being spammed in dmesg

amdgpu: [powerplay] 
                failed to send message 282 ret is 254


I loose write acess to 
/sys/class/drm/card1/device/hwmon/hwmon1/pwm1_enable

it is stuck on 2 , and runs the fans super low @ 20% causing the GPU to reach
thermalmelt down 96 deg when the fan will do blips of 100% 
my bios was modded to even have a minimum fan speed of 50% and even this is
being over written 

/sys/class/drm/card1/device/hwmon/hwmon1/pwm1
also can not adjust 



GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.ppfeaturemask=0xffffffff amdgpu.dc=1
amdgpu.gpu_recovery=1 amdgpu.cik_support=1 amdgpu.dpm=1 radeon.cik_support=0"


if I reboot it works for a little while allowing me to change GPU speeds and
fan speeds then .. I loose fan speed control and can not get it back off auto ,
which seems to be setup with fans speeds way too low 


 GL_RENDERER:   AMD Radeon R9 200 Series (HAWAII, DRM 3.33.0,
5.3.8-050308-generic, LLVM 9.0.0)
    GL_VERSION:    4.5 (Compatibility Profile) Mesa 19.3.0-devel (git-ff6e148
2019-10-29 bionic-oibaf-ppa)


if I disable amdgpu.dpm I can control the fans but then I can not do Auto GPU
speeds and can not manually do my speeds 


my only guess is the firmware being loaded by kernel is the place containing
the info for fan speeds ?
