By the way, please use a recent kernel. Seeing edge here means you're
running with something that is a bit old (and broken). And since you
haven't even said what revision of the kernel you're using, hslping you
is not an easy task. tglx told you something similar about a week ago.

Aren't legacy interrupts supposed to be *level* triggered, and not edge?
