interrupt statistics (broken hifn ?)

[Mike Tancsa]

Hmmm Indeed this seems to be the case. I guess the next question is, what 
would cause the hifn card not to work in 3 machines despite showing up?

hifn0 at pci1:2:0: class=0x0b4000 card=0x00000000 chip=0x001213a3 rev=0x01 
hdr=0x00
     vendor   = 'HI-FN Inc.'
     device   = '7951 Security Processor'
     class    = processor

On another machine it doesnt show up I imagine because its a shared interrupt
