I have been using 2.6.21.1. It seems working well, that is, all my
disk partitions are mapped as "/dev/sda*" and the performance looks
good. After I upgrade to 2.6.22.5 with the exact same configuration,
all the disk device turn to "/dev/hda*" and the performance degrade
obviously.
While I boot with 2.6.21.1, the logs regarding disk are:

It seems the dramatic change in libata.c incurs this failure.

It looks like you have some CONFIG_IDE options enabled in your kernel
configuration that result in drivers/ide trying to drive part or all of
that controller, preventing libata from doing so. Likely the easiest
thing to do is just set CONFIG_IDE=n entirely..

The SATA works with 2.6.22.5 after CONFIG_IDE =n being set.
Thank you very much.
