I have an older DPT, but I still want to add my experiences to the above: (1) I've had my array (a 2GB RAID1 - personal RAID :-) run in degraded mode. This has worked just fine with the driver in -current, with the RAID full (of partitions, not data. I can't understand that the amount of data should make a difference - the controller shouldn't know about this anyway). (2) The DPT controller on this has reported alternating wrong sense of the disk setup to the BIOS. This is obviously NOT a driver problem. As for your problems, I'm sorry to hear about them, but have no idea how to fix it. I've had none of the problems you have :-( Eivind.
