HI, PMC won't help with the interrupt storm. We need to go see what the "stuck" bits are in the arge_intr() / arge_intr_filter() routine. I'll go add some debugging tonight to count each interrupt bit. That should tell us which bit it is. I wish I could reproduce it here. I'd fix it really quickly :( -adrian
