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.
