Not even an analog camera, but with or without the above, I get a single:

... and when I add "debug" as a kernel param so that I actually get to
see them (doh) I get the same as Laurent:

I tried just ignoring more ACKs in i8042_interrupt() but that didn't do
anything other than alternating between 2 and 1 i8042.c printks between
atkbd.c printks when ignoring an even or oneven number, respectively. I
guess it's atkbd.c which needs to ack something to keep it from just
being delivered over and over again or something like it?
If I apply the following, things seem to be working for me; no "Spurious
ACK" messages anymore (but a steady stream of fa's from i8042). Not a
real fix, but I hope it's enough of a clue for someone who understands
the infrastructure here. Vojtech added to CC as well.
I by the way also tried plugging in a PS/2 mouse (I normally use a USB
mouse), adding atkbd_reset=1 to the kernel params and lifting the
if (!flags && data == ATKBD_RET_ACK)
atkbd->resend = 0;
out of the ! __i386__ define. No help.
