In the attached log, the amdgpu driver is too noisy. Would it be
possible to disable the amdgpu and radeon drivers for this test? So only
simpledrm should be active. Likely this doesn't produce any graphical
output and you may have to be able to login remotely to get the log.

Please find attached dmesg log without amdgpu/radeon drivers.


Oh, now simpledrm itself fills up the log with pointless messages. :/ Looking at the file, there's plenty of Gnome buffer swapping. I suspect that Gnome works? It's just the console that's not available?

Could you please boot directly into a text terminal? That should be possible by adding systemd.unit=multi-user.target to the kernel command line if your distro uses systemd. Due to the issue, you probably won't see anything on the screen, so you may need remote access.

Thanks for your help with debugging and sorry for sending you through so many hops.

Best regards
Thomas
