Timed out while idle generally means that we sent a command to the disk, but it didn't respond before the timeout for that command fired. In the case of reads and writes from the da(4) driver, the timeout is 60 seconds, which is plenty long enough for any disk. So it's likely your disk is going "out to lunch" and not coming back. What sort of disk is it? You might consider replacing it.
