The cable the disks are on is a preterminated LVD from Adaptec. We replaced it at least once (possibly twice; I can't remember) with another preterminated Adaptec LVD cable trying to cure this problem, but to no avail. Forgot to mention that we see this error a dozen or so times per day. FWIW, on another machine we occasionally see the same problem on another machine with the same motherboard, but not in the last week (don't have logs further back than a week).
