Is it expected behaviour that ahci performs a time-out during boot, even
though camcontrol indicates success? This is on 8.1-PRERELEASE csup'ed
today.
I've enclosed dmesg, camcontrol and pciconf information. The timeout is
approximately 12 to 14 seconds for each connected disk-drive. If I
run with only usb devices, there are no timeouts. The following
dmesg is when I connect two HDD's on a VIA SN18000 motherboard, and
the BIOS has ahci selected, i.e. not IDE nor RAID.
These machines are personal servers and are permanently running.
# dmesg | egrep -i "ahci|ada"
