I've also been getting this, albeit very rarely. It doesn't seem to happen with older firmware (ie. Jul 14th firmware extracted from Fedora's linux-firmware package), only the newer firmware from the ~agd5f/radeon_ucode repo causes this. I figured maybe it had to do with PCIe bandwidth, but it occurs on 3.0 as well as 4.0. Even occurs with system-wide AMD_DEBUG=nodma in my /etc/environment. There is no amdgpu error in journalctl, just the above. Screen freezes & I have to reboot with REISUB. Perhaps this is a different issue, and if so, perhaps we should make a separate bug report for it?
