I recently upgraded several systems from gentoo-sources-5.10.76-r1 to 5.15.11, using my usual approach
copy current config to new sources
make oldconfig
all modules_install install
run dracut
reboot
All worked well except my desktop, which just sits there showing
EFI stub: Loaded initrd from command line option
So the bootloader has loaded the kernel but then there is absolutely
nothing. I tried removing the initrd option, but then it went straight to
a blank screen without the above message. I left it for a while, in case
it was just a case of no output, but nothing happened, not disk or
network activity, nothing.

Did you touch the new frame-buffer settings? I did at first and got
something like your experience, but then after a distclean and oldconfig, making sure to leave the new frame buffer at their defaults, everything now works.
I'll look into how it's supposed to work when I get back home.

I also ended up with a blank screen followed by a reboot, which showed
some partitions were not unmounted cleanly, followed by repeated
reboots in the same fashion, until I interfered to stop this madness.
I then booted with the previous kernel and as my first task I disabled
some framebuffer setting, which I now fail to recall! LOL!
I think it is this one:
=======================
CONFIG_DRM_SIMPLEDRM:
DRM driver for simple platform-provided framebuffers.
This driver assumes that the display hardware has been initialized
by the firmware or bootloader before the kernel boots. Scanout
buffer, size, and display format must be provided via device tree,
UEFI, VESA, etc.
On x86 BIOS or UEFI systems, you should also select SYSFB_SIMPLEFB
to use UEFI and VESA framebuffers.

CONFIG_DRM_SIMPLEDRM:
I don't have that one set. About the only framebuffer I have set is CONFIG_FB_EFI and changing that makes no difference.
I'm not convinced it is display related as I do get the initial message
from the bootloader displayed as normal.
