ATA driver cannot detect the Serial ATA disk in FreeBSD/AMD64-Current

My system is consisted in Tyan S2885 opteron dual board and Seagate 7200.1 SATA
disk with
FreeBSD/AMD64 5.2-Current.

Old ata driver could detect the disk. Below the verbose message on bootstrap:

But, new ata driver cannot detect the disk.

Therefore, My system cannot be bootstrapped new ata driver. (root in ad4s1a)

Anyone help me.
