my bad. the last working amr/iir is from March 12.
I first detected the problem sometime later, but not later than March 23.
So it has to be changes in that time frame.

both drivers are showing similar symptoms:
	waiting for not busy
the iir goes on for ever, and it's the cam that eventually panics,
 run_interrupt_driven_hooks: still waiting after 300 seconds for xpt_config
(actually not 100% true, depending if WITNESS is on or off, it sometimes
just hangs).
the amr seems to time out:
	amr0: adapter is busy

thanks for looking into the problem,
