I still have the same issue with this kernel as the previous 5.13.x kernels. Blank screen on changing framebuffer.

BZ#1985598

Doesn't work for me with my AMD 5600M graphics card.

See https://bugzilla.redhat.com/show_bug.cgi?id=1985598 for more information but it looks as though there are a few problems with AMD Graphics, which are problems when I use the 5.13.x kernel

1. I had to uncompress the amggpu/navi10_smc.bin.xz file on the initrd for it to load else it would fail to load the firmware.
2. Unable to change FB to use the amdgpudrmfb, but if I use the kernel boot parameter 'nomodeset' then it boots.

I am running a DELL G15se G5505 model and with the updated 5.13.4 kernel has issues booting. If I run the older 5.12.x releases then there is no issue.

The issue resides in booting the kernel and it stops with

fb0: switching to amdgpudrmfb from EFI GPU

It appears the console stops displaying commands but I am able to CTRL-ALT-F4 and use CTRL+ALT+DEL to restart and pick the older 5.12.x kernel from the grub boot menu.

I have logged in with Bugzilla via ticket:
