Sometimes I get several of these per second. Sometimes there are none for a few
minutes.
If I boot into runlevel 3 (i.e. without starting X) I get one of these during
boot, but then there are no more after that.
I'm running Ubuntu 20.04 but I also saw this on 18.04.
Kernel version is 5.4.0-42-generic but I also saw this with 5.3.0-51-generic.
I'm using the amdgpu-pro drivers.
Graphics card is a Navi 10.
Motherboard is a Gigabyte X470 AORUS ULTRA GAMING.
CPU is an AMD Ryzen 9 3900X.
