--- Comment #5 from Tony Chaveiro (tchavei@gmail.com) --- I experience the same issue
4.18-20 kernel on Manjaro (amdgpu + opencl taken from amdgpu pro on 3 x R9 390). Everything works fine. Fan rpm increase with load (tested with stak-xmr miner).
4.19-8-2 kernel: Rpm fans always on minimum setting. Once one of the gpus hits 95C, sudden bursts of 100% rpm occur (under 1s duration). Application has to be suspended or hardware damage will occur
checked pwm1_enable which displays "1". Changing to "2" has no effect. pwmconfig drives fans to 100% during config but is unable to provide control.
pwm1 reads different values (from 86 to 127) but fans don't appear to change speed at all.
