Linux amdgpu 19.30-838629 spams syslog with errors

Getting the following syslog spam every 1 seconds with RX 5700 card installed in system:

kernel: amdgpu: [powerplay] Failed to send message 0x0, response 0xfffffffb
kernel: amdgpu: [powerplay] Attempt to get current RPM from SMC Failed!
kernel: amdgpu: [powerplay] Failed to send message 0xe, response 0xfffffffb, param 0x80

AMDGPU installed from provided driver .deb packages with installer script. dkms build finished without errors. Hardware and OS specs are as follows:

 

mobo: Gigabyte X399 Designare EX with latest bios (F12g)

cpu: Threadripper 2920X

ram: 8x 16GB Samsung ECC

gpu: MSI RX 5700

os: Ubuntu 18.04.2 LTS

kernel: 5.0.0-16-generic (hwe-edge stack)

 

It appears that the driver doesn't provide any facilities for limiting log messages, which would be very useful in a situation like this.

 

Also, running 'sensors' gives the following error:

 

$ sudo sensors
