xhci broken on 10-CURRENT and 2013 MacBook Air?

[Lundberg, Johannes]

Hi

I'm trying to install 10-CURRENT on a 2013 MacBook Air and there seem to be
some problem with the xhci driver.

During boot of the memstick image of current from 20130818 I get either of
the following errors:

- Boot freezes during probe of xhci devices.
- Probing times out (immediately) and I get the mountroot> prompt but no
functional keyboard.

I tried an image of 10-current from May but the problem is the same so what
ever change that made this stop working was committed before May.

I also tried disabling xhci with the following steps but without success

- Enter boot prompt
- set hint.xhci.0.disabled=1
- load ehci / uhci
- boot

The 9.1 release successfully detects all usb devices during install but
stop working at the partitioning tool because the PCIe SSD drive isn't
detected. Using 9.1 as LiveCD I managed to pull out the following
information.

MacBook Air 2013, FreeBSD 9.1 LiveCD

Anyone has any clue what's going on?
