I also get this when booting - think it started happening when I started
using the new ata-driver. For me it happens when the root is supposed to be
mounted (from dmesg):
<snip>
atapci0: <Intel PIIX3 ATA controller> port 0xffa0-0xffaf at device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
<snip>
ad0: 2015MB <ST32132A> [4095/16/63] at ata0-master using WDMA2
ad2: 814MB <Maxtor 7850 AV> [1654/16/63] at ata1-master using PIO3
acd0: CDROM <CD820E.0v1098300> at ata0-slave using PIO3
Mounting root from ufs:/dev/ad0s1a
ad0: READ command timeout - resetting
ata0: resetting devices .. done
ad0: READ command timeout - resetting
ata0: resetting devices .. done
ad0: READ command timeout - resetting
ata0: resetting devices .. done
ad0: READ command timeout - resetting
ata0-master: WARNING: WAIT_READY active=ATA_ACTIVE_ATA
ad0: trying fallback to PIO mode
ata0: resetting devices .. done
and then everything proceeds as normal.

As you can see I am using a seagate disk and I am having the same problem.

There are probably many people out there affected by this so I really think
it ought to be fixed - preferably before -RELEASE.
