It appears at this point in the boot process the keyboard (USB and
PS2) are not yet available and/or do not respond in this scenario (I
do have CONFIG_MAGIC_SYSRQ enabled+have used it in the past).  I'll
build the prior 5.15-rc(1-7) to check where it stopped working and
reply back to the list when I have that info.

Thanks!

Justin.
