I am not sure, but D3 is a good guess. It is all a workaround as the
real fix should be in Apple's UEFI implementation. I think it is
unlikely we can make them do that although we probably supplied them
the wireless part.
Disabling busmastering and then D3ing the device once in the kernel
didn't seem to work, but putting the device in D3 while in the firmware
(and leaving busmastering enabled) seems to avoid the problem.
Yup, the master disable itself hangs the device. The device should be
able to deal with going to D3 so you could try just doing that from the
kernel.
