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!
