You have good taste in laptops. :)
Does anyone have any ideas? I've tried essentially all variations on the
"UEFI Troubleshooting" guide
I have a Thinkpad T14 with a Ryzen 4750U on its way. These new Ryzen
APUs are becoming popular... its going to become a real sticking point
to get them working with Qubes!
A user named Claudia had a long thread about installing Qubes on a
previous gen Ryzen...

Also worth noting is that some Ryzen 4000 power management drivers have
just landed in Linux 5.8.

When trying to install Qubes 4.0.3 or 4.1 (Test ISO) into a Ryzen
4750U based laptop, I see xen output, it relinquishes vga to dom0,
then black.
I managed to enabled logging, where it prints dom0's dmesg super
slow, line by line.

Then it crashes but it continues to come all the way to Anaconda
confirming it's a GPU/Memory Issue
This seems to be related to UMA / iGPU Memory Management, unsure if
it's just that Kernel Support for this CPU is spotty, Fedora 32 Live
USB boots perfectly.
This is 100% a Display/GPU issue has everything else comes up
smitten, I just don't see anything / the framebuffer isn't passed
from Xen to dom0.
