I get periodic errors like this in dmesg, which coincides with intermittent system stalls: [Wed Sep 4 00:43:43 2019] amdgpu: [powerplay] Failed to send message 0x12, response 0xfffffffb param 0x6 [Wed Sep 4 00:43:43 2019] amdgpu: [powerplay] Failed to export SMU metrics table!

I'm running kernel 5.3-rc7 GPU: Sapphire Pulse RX 5700XT (Navi 10) with firmware from https://people.freedesktop.org/~agd5f/radeon_ucode/navi10/ Distro: Debian testing / KDE. I noticed, that it starts happening often when I'm using ksysguard, which queries lm-sensors for amdgpu temperature and fan speed.
These errors also happen when using radeon-profile to control the fan speed: [ 3099.422315] amdgpu: [powerplay] Failed to send message 0xe, response 0xfffffffb param 0x80 [ 3099.422318] amdgpu: [powerplay] Failed to export SMU metrics table!

Are you running a monitor at 75hz? I can only trigger the bug when setting 74-76hz with amd-staging-drm-next, and although I haven't tested in a while, I suspect the same applies with 5.3-rcX (and drm-next-5.4). Here's the output after setting 75hz, on amd-staging-drm-next: [ 7937.682003] amdgpu: [powerplay] failed send message: TransferTableSmu2Dram (18) param: 0x00000006 response 0xffffffc2 [ 7937.682004] amdgpu: [powerplay] Failed to export SMU metrics table!

I can confirm this happens when I use a dual-monitor setup. I have two 1440p@144 Hz screens and these messages happen when I boot with both screens, or look at the gpu temperature through the sensor command, with both screens active. With only one screen active, I cannot reproduce the bug.
Just for the reference, my connection is DisplayPort 1.2.
I ran into this issue when messing around with my BIOS settings. Not sure if helpful but when I had the option Decode Above 4G (64bit adressing on PCI bus?) on my Gigabyte Aorus B450 I experienced the same issue. After turning that option back off everything is working again.
I don't get these errors anymore when using radeon-profile with kernel 5.4-rc6. But with ksysguard, Failed to export SMU metrics table! message is still occurring, though it's not causing any stalls or hangs now.
