--- Comment #4 from Warner Losh <imp at FreeBSD.org> ---
If you do, you'll have to add this device to the quirk list... I suspect some
other issue is going on since the device is likely transitioning from power
state D3 to D0. I haven't checked, but sometimes that takes a while and it's
quite possible there's an other spot in the driver that needs either a fixed
delay (yuck) or to poll something to become active before proceeding.
