    I sent this to freebsd-questions earlier via the newsgroup, but I just
    found out today that the list-to-news gateway has been down for half a
    month now. Any idea when it's going back up? Who was hosting that service
    anyway?

    And now for the question..

    I have a test server that is being used to test a 4.4-REL to 4.8-STABLE
    upgrade, and I've found the system will no longer boot unless I load a
    saved 4.4-REL kernel. The error I get is along the lines of:

    Mounting root from ufs:/dev/ad4s1a
    Root mount failed: 16

    At first I got this error using a custom kernel configuration known as WWW,
    but after getting this error I built a new kernel based on GENERIC:

    # cd /usr/src
    # make update
    # make buildkernel
    # make installkernel
    # reboot

    Per /usr/src/UPDATING there was a change in the ATA drive at 4.5-REL, but
    it mentioned running mergemaster to create the new devices, and according
    to /usr/src/Makefile I shouldn't do that until I get past the current stage
    (which is where I am stuck):

    (/usr/src/Makefile comments)
    1. cd /usr/src
    2. make buildworld
    3. make buildkernel
    4. make installkernel
    5. reboot
    6. mergemaster -p

    This machine does have the Promise RAID-1 IDE controller that is built into
    a lot motherboards these days. Here is my dmesg output from this server on
    a successful boot:

    ar0: 39266MB <ATA RAID1 array> [5005/255/63] subdisks:
       ad4: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata2-master UDMA100
       ad6: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata3-master UDMA100

    However, this test machine mimics how the web servers were setup, and they
    do not use /dev/ar, but instead use /dev/ad0:

    # cat /etc/fstab
    # Device Mountpoint FStype Options Dump Pass#
    /dev/ad4s1b none swap sw 0 0
    /dev/ad4s1a / ufs rw 1 1
    /dev/ad4s1f /usr ufs rw 2 2
    /dev/ad4s1e /var ufs rw 2 2
    /dev/acd0c /cdrom cd9660 ro,noauto 0 0
    proc /proc procfs rw 0 0

    I am thinking that in 4.5-REL or newer (we are trying to upgrade to 4.8)
    that things might have changed? Again, /usr/src/UPDATING mentions some
    changes to the ATA code, but nothing specific to our configuration.

    Any ideas here?

    Following are the partition and disklabel information for /dev/ad4 and
    /dev/ar0:

    parameters to be used for BIOS calculations are:
