Thanks so much for testing! I'll need to look more into why this fails on Alpha then.

In order to prevent file system corruption on disks attached to 32-bit ISP1020/1040 cards in 64-bit enabled systems, while maintaing the possibility to run other qlogic cards in 64-bit mode, limit DMA_BIT_MASK to 32-bit.
