I suspect it's a hardware problem. The above message is from the DPT driver's timeout handler, and it is complaining about a particular disk or array you've got setup. The timeout for read and write operations from the DA driver is 60 seconds. So that means that da0 didn't complete a read or write in 60 seconds. What sort of disk is da0? There are some disks that are known to lock up under heavy I/O.
