I have seen a problem, with a different adapter and arch but similar
symptoms, where 5.14 worked and 5.15 did not. That was tracked down to a
difference in IRQ domain handling between the two kernels, resulting in
an IRQ essentially not working anymore. The fix was arch-specific and
not x86_64, but might be of interest:

That's hard to say. Is CONFIG_MAGIC_SYSRQ enabled? If not, please enable
it and hit Alt-Printscreen-t (dump task list; see also
Documentation/admin-guide/sysrq.rst) and share the contents of the
kernel log. If that would not be convenient, please try to bisect this
issue.

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.

I have tried all of the -rc's and they all hang at boot, keyboard
input (USB/PS2) is not working at this stage in the boot process.
Are there any thoughts on how to debug this further?
