Hi,
I've installed -CURRENT using snapshot "FreeBSD-15.0-CURRENT-
amd64-20250213-6156da866e7d-275409" on an HP EliteBook 845 G10 with AMD
Ryzen 5 7540U.
Both when booting from the install media and when booting from disk
after installation I get a very poor boot performance up until the
FreeBSD Boot Options Menu. Right after it is all OK.
I've recorded what happens during the boot from the installation media
in [1].
Does this ring any bells ? Is it a bug that I should report in a PR
(Problem Report) ?

This happens because UEFI framebuffer access from boot loader is very
slow. Once the kernel is loaded and booted, everything is okay because
we properly set memory attribute. It's a long standing bug and there's
PR254381.
