I am not sure what you mean by both being blocked at the same time, and I don't know what I should do about it. I have two sata controllers, and I put one of the source raid disks on each controller. I thought that this would improve reliability and perhaps performance. This means that the backup target disk shares a controller with one of the source disks. It appears that the drive that reset is on the second controller with the backup target disk (how do I confirm what contoller the devices ata8.00 and ata9.00 belong to?). I would appreciate any suggestions on how to triage this problem as being either 1) hardware that should be replaced (easy) and close this bug report; or 2) driver related that needs to be watched for in case it happens again.
