--- Comment #35 from Michael (lkb...@deegan.id.au) ---
I discovered a workaround that works for my R9-290 and Debian 5.3.0 kernel:

  root@joyola:~# echo "2"
>>/sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable 
  root@joyola:~# echo "0"
>>/sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable 

pwm1_enable will still be 2 afterwards, but (after spinning the fans at max for
a bit) automatic fan control works for me. I also have to do the same
pwm1_enable prodding after resuming from suspend.

(If it matters, I boot with radeon.cik_support=0 amdgpu.cik_support=1
radeon.si_support=0 amdgpu.si_support=1 amdgpu.dc_log=1 amdgpu.gpu_recovery=1)

I still have the same brokenness as reported in comment 14 though.
