Description Junichi Satoh 2000-10-07 06:50:01 UTC 
SiS5571 does not have ATA33 mode.
But, it is probed as SiS5591 ATA33 controller like below.
------
atapci0: <SiS 5591 ATA33 controller> port 0x4000-0x400f,0x374-0x377,0x170-0x177,0x3f4-0x3f7,0x1f0-0x1f7 irq 14 at device 1.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
------

It fallback to PIO mode. So it does not work on ATA mode.

How-To-Repeat: 
# mount /dev/ad0s1e /mnt
ad0: READ command timeout tag=0 serv=0 - resetting
ata0: resetting devices .. done
ad0: READ command timeout tag=0 serv=0 - resetting
ata0: resetting devices .. done
ad0: READ command timeout tag=0 serv=0 - resetting

ad0: trying fallback to PIO mode
ata0: resetting devices .. done
