While investigating the slow hard drive on my MacbookAir6,1, I decided to take a working installation of -current (20141201 snapshot) on a USB drive and try booting it on the MBA6,1. I discovered that booting off of a usb drive (with a full install, i.e. bsd.mp NOT bsd.rd) hangs once the boot reaches this line:
uhub0 at usb0 "Intel xHCI root hub" rev 3.00/1.00 addr 1 This behavior manifests while using a 'normal' boot--I did not use the OSX bless utility to get the builtin USB controller into ehci mode instead of xhci mode. When I *do* do that (use bless to set the usb controller into ehci mode) the boot progresses to: scsibus4 at softraid0: 256 targets then pauses there for 5 minutes, then proceeds to boot just fine. When booting this way, I observe the same pauses/slowness when operating on the builtin hard drive as mentioned in the thread I started on that topic: http://marc.info/?l=openbsd-misc&m=141747241629431&w=2 Anyway, I mention the xhci boot hang behaviour because I know xhci development is active, and I thought this result may be interesting/useful for that. Here is the dmesg from this laptop: OpenBSD 5.6 (RAMDISK_CD) #303: Fri Aug 8 00:25:26 MDT 2014 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/RAMDISK_CD RTC BIOS diagnostic error ff<clock_battery,ROM_cksum,config_unit,memory_size,fixed_disk,invalid_time> real mem = 8511332352 (8117MB) avail mem = 8279367680 (7895MB) mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.4 @ 0xe0000 (42 entries) bios0: vendor Apple Inc. version "MBA61.88Z.0099.B16.1408291503" date 08/29/2014 bios0: Apple Inc.
