    Like many people I was confronted with "TIMEOUT - READ_DMA"
    and "TIMEOUT - WRITE_DMA" errors on my drives. I was frustrated.
    But I found a workaround: Turning off ACPI.

    I just received a Highpoint RocketRaid 1640 controller,
    2 Maxtor 300GB drives, and a Supermicro 5-drive SATA cage.
    I am testing this configuration for a storage server.

    I am using an old motherboard, DTK brand, Slot 1. 300A Celeron.

    Under a fresh install of 5.3-RELEASE I am unable to read or write
    both drives heavily at the same time. One drive alone seems to work
    OK. When I run dd blasting both drives with seqential IO, I get
    TIMEOUT - WRITE(READ)_DMA. Repeatably, within 15 seconds.

    However I got a good test before I installed 5.3-R, the box was running
    with 5.3-BETA. Only difference was I booted without ACPI.

    So I rebooted the freshly installed 5.3-R without ACPI, and It works!
    I can read at 50MB/s per drive concurrently (hitting PCI bus speed
    limit?), and write at 30MB/s per drive concurrently. No errors so
    far, and its been dd'ing for a half hour.

    I hope this report helps someone!
