Yes, this is familiar. Several people have reported problems with Seagate's 7200.10 disks in 3Gbps operation on sata_promise. Unfortunately the error reports don't really give a clue as to what the root cause is. I used to be able to forcibly trigger similar errors with their 7200.9 disks, but I can't seem to do that any more. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
