Yes, it should be >= 32 :-)

Sure.

The basic gist of the problem seems to be that when the chip is
brought up, the initial request_irq() forces a lingering interrupt
status in the chip to have somewhere to go.
But the IDE layer refuses to do something to clear it because it's
not expecting any interrupts (this is the: cur_port != hwif).
Some things other than the commit in question have changed in the area
of interrupt and chip initialization and I'll try to go through
the commits to get some clues.
Thanks!
