>Description:
After an update from RELENG_7 neither the SATA controller nor any of the drives
were recognized, hence the system was unable to mount the root partition
(/dev/ufs/2root alias /dev/ad4s2a).

After deactivating SATA Native Mode in the BIOS (HP Compaq 6510b notebook) the drive was back (now as ad0), however I consider this a workaround, not a solution.

Here's some information about the system:
# pciconf -lv | grep -i sata -C5
    device     = '82801HEM (ICH8M-E) LPC Interface Controller'
    class      = bridge
    subclass   = PCI-ISA
atapci0 at pci0:0:31:2:	class=0x010180 card=0x30c0103c chip=0x28288086 rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82801 (ICH8M) 3 port SATA Controller'
    class      = mass storage
    subclass   = ATA
wpi0 at pci0:16:0:0:	class=0x028000 card=0x135c103c chip=0x42228086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Intel 3945ABG Wireless LAN controller (10208086)'

This is from the RELENG_7 dmesg:
atapci0: <Intel ICH8M UDMA100 controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x40c0-0x40cf irq 16 at device 31.1 on pci0

This is from the RELENG_8 dmesg in SATA native mode:
atapci0: <Intel ATA controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x40c0-0x40cf irq 16 at device 31.1 on pci0

This is from the RELENG_8 dmesg with SATA native mode deactivated:
atapci0: <Intel ATA controller> port 0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0x40c0-

UDMA33 doesn't really sound like full speed.
I have the following line in my rc.local for the DVD drive:
/sbin/atacontrol mode acd0 WDMA2
