I got the timeouts with STABLE as well, that was the reason for me to try out CURRENT. I'm sorry I didn't mention that earlier. My main concern is to get rid of the timeouts, but a panic on one can't be right. How can I debug this further? I can get timeout fairly consistent by putting a bit of load on the drives. If it would help I can also provide remote access. I'm trying to update the firmware on some of the drives now to see if that helps with the timeouts. -- Ståle Kristoffersen
