You didn't say what interrupt you were using.. I assume it's has to
do with the keyboard interrupt, are you just hooking into the interrupt
or are you attempting to service it your self and forget the other guys
down the line. With out knowing more I would say you are not issuing 
the Non-specific Interrupt Clear to the 8059 but that about all I can
say.
Be more specific about what you are tring to do here.. Interrupts on
the PC machines are screwed up at best (for those of you that
don't think so, try messing with the EGA interrupt).
