I tried HighPoint HPT 370A (Adaptec 1200A), HighPoint HPT368, Promise PDC20270 (FastTrack 100Tx2), and the PDC20276 built onto the motherboard, and a HighPoint HPT302 which didn't work properly at all. I still got the lockups with various permutations of the non-Silicon Image chipsets, and found that to my amazement, the Silicon Image 680 chips gave the best performance. I too had major problems with CMD64x boards on a production 2-CPU system (server for student accounts), so remained with SCSI on that machine. Bugzilla for the kernel? I didn't know there is one! I'd better find it.
