That's suspicious. AFAIK the Amiga keyboard doesn't generate any keycode
greater than 103. Where does this code come from?

The only input source for wskbd is the keyboard interrupt handler in kbd.c.

Unfortunately you cannot use "vmstat -i", but I would bet that you have more
level 2 interrupts than just from the keyboard.

What you and Chris Edwards, who reported the problem before, have in common
is a PCMCIA card plugged in. Does such a card generate level 6 or level 2
interupts? Did you already try without it? Or is there any other additional
interrupt source (SCSI? Should be level 6, though).

I guess I will insert some debugging output in the level-2 interrupt handling.
