[rx 6800 xt] Crashes on boot with linux-firmware commit bec4fd18cc57b262241cd4578ed4533ca23ed0c3

Brief summary of the problem:

When using linux-firmware https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=bec4fd18cc57b262241cd4578ed4533ca23ed0c3 with kernel 6.10.6, booting into sddm displays only the left half of the screen and when booting into recovery tty after a few seconds the screen goes black and then completely off continuously every few seconds. This happens every boot and the dmesg contains lines like:
