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
