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 :(
