UEFI black screen stall

[Master Node]

Hey I recently made a post about x start up failing, I'm thinking this was from trying to run a raid configuration between two m2 drives in a sata adapter case. After I stopped doing that I have not seen the same error.

Now I am onto another problem and can just taste qubes os finally working again lol, this problem happens after install reboot, everything goes good untill it hits the finaly boot up and goes to a black screen and freezes, I have tried to do the

mapbs=1
noexitboot=1

Work around adding it under both kernels when I reboot it doesnt do anything and I get the same black screen.

If you are a pro at qubes you can msg me direct as well and i have no problem throwing you some money if you can expediate my head aches. Or you can comment here as well both work either way.

I guess anything is possible. Glad to hear it's solved.

I'm not sure if those apply to legacy mode.

Try pressing f12 repeatedly during startup, about when you see "Loading
initial ramdisk..." in grub. This should get rid of the graphical splash
screen and switch to console output. Take note of the last few lines on
the screen when it freezes. Alternatively you can remove "rhgb quiet"
from the command line in grub.

Is the whole system frozen, or just the screen? Does the light turn
on/off when you press caps lock, for example? If you press
ctrl-alt-delete does it power off after some time?

I recently had the same problem, where Qubes 4.0.2 would screen freeze
during boot. I went through the above steps and eventually found
"nomodeset" to work around the problem, due to a bug in the amdgpu
driver. Other people with my same laptop found that "iommu=soft" kernel
option would allow the amdgpu driver to load without freezing, at least
on regular non-qubes non-xen linux. I don't know if/how kernel iommu
options work in Qubes.

If you're using Qubes version earlier than 4.0, make sure to add
iommu=no-igfx to the Xen command line.
