This patch moves power up/down out of port init/deinit and call them

Berck, can you please test this patch? This might fix your problem
too. Jeff, this patch is necessary regardless of Berck's repsonse. I
think this should go into #usptream-fixes too after some testing in
#upstream (and in -mm).
Nope, that doesn't do it. All along I've also been getting weird
messages on system power-downs. I just now set up a serial console to
capture them. I dunno if they're of any significance, but they're on
the same device that pauses on boot, so perhaps they're related.
Berck
Will now halt.
