ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=207594611

Hi,

My 6.0-CURRENT box says, such as

ad0: TIMEOUT - READ_DMA retrying (2 retries left) LBA=207594611
ad0: WARNING - READ_DMA no interrupt but good status

I replaced the ad0 with brand-new HDD, but I still got same messages.

The box has 3 HDDs(ad0,ad1,ad3) and DVD(acd0) drive, but the messages
comes only from ad0.

What is happening?
Cable problem or ATA controller problem?
