Here is the output:

I was afraid of that.  That's your pdcide controller. 
You're
getting a steady stream of interrupts from it because we're
not
properly clearing the interrupt somehow / for some reason.

So the "bogus intr" is still affecting you--it's
just not entirely
crippling.  I might be able to find some time to look at
this some
more in a few days, but can't right now.
