This log might be a better one to look at. I tried booting several
times, each boot was EXACTLY the same, no blacklisting of the radeon
driver, no use of modeset=0 or other boot parameters. The only variable
was the time delay between getting the GRUB menu and pressing the enter
key on the menu to get the boot to occur.

The very last boot (time entry 20:50:16) resulted in a successful boot.
I believe all the others resulted in a black screen.

I used drm.debug=0x0e for all boots.
