I am trying to install 5.6-release on a MacbookAir6,1. There are long (5 to 10 minute) pauses that seem to happen whenever the OS accesses the built in hard drive. I tried the 20141201 snapshot as well and observed the same pauses. The pauses/slowness is so long that after 4 days of waiting, I wasn't through the step of the installer where the file systems are written out.
I kept a manual log of my most recent attempt to install 5.6.release, including timestamps to help illustrate the long pauses: ??:?? <follow jcs suggestions at https://gist.github.com/jcs/5573685 to create a partition using bootcamp then use bless to boot to usb isostick with install56.iso> 09:?? <boot install56.iso using USB ISOstick> 09:17 scsibus2 at softraid0: 256 targets 09:20 (I)nstall, (U)pgrade, (A)utoinstall or (S)hell? s\n 09:28 # fdisk -e sd0\n 09:38 fdisk: 1> ... 09:41 fdisk: 1> setpid 3\nA6\nquit\n 09:45 Writing MBR at offset 0. 09:53 # ... 09:55 # disklabel -E sd0\n 10:01 Label editor (enter '?' for help at any prompt) 10:01 > ... 10:11 > a a\n\n\nRAID\nq\n\n 10:20 # ... 10:56 # bioctl -cC -l /dev/sd0a softraid0 11:02 New passphrase: <password>\nRe-type passphrase:<password>\n 11:07 sd2 at scsibus2 targ 1 lun 0: <OPENBSD, SR CRYPTO, 005> SCSC2 0/direct fixed 11:07 sd2: 415800MB, 512 bytes/sector, 851559920 sectors 11:08 softraid0: CRYPTO volume attached as sd2 11:08 # ... 11:14 Available disks are: sd0 sd1 sd2 11:14 Which disk is the root disk?
