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 dmesg output xhci0: <XHCI (generic) USB 3.0 controller> mem 0xb0a00000-0xb0a0ffff at device 20.0 on pci0 pciconf -l output xhci0@pci0:0:20:0: class=0x0c0330 card=0x72708086 chip=0x9c318086 rev=0x04 hdr=0x00 usbconfig output ugen0.1: <XHCI root hub 0x8086> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=SAVE ugen0.2: <BRCM20702 Hub Apple Inc.> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=SAVE ugen0.3: <product 0x820a vendor 0x05ac> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen0.4: <product 0x820b vendor 0x05ac> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen0.5: <Bluetooth USB Host Controller Apple Inc.> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen0.6: <Apple Internal Keyboard Trackpad Apple Inc.> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen0.7: <USB Flash Disk BUFFALO> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps) pwr=ON ----- Anyone has any clue what's going on?
