I see this as well with two identical SATA drives on an Intel 875PBZ motherboard. The drives last worked reliably with sources just prior to 5.2-RELEASE, and prior to that, just shortly before 5.0-RELEASE. (Notice a pattern? ;) ) You may want to try older sources. Also, I have had good luck with Doug Ambrisko's ATA patches, although I haven't tried to investigate which part of the patch fixes the problem. If I have some time this summer, I'll try to deconstruct one of Soeren's mega-commits to figure out exactly what change broke the ATA driver for my hardware. Unfortunately, I usually get disk corruption when the machine locks up, so the problem is painful to reproduce.
