error code with ASC/ASCQ 4/1 (``Logical unit is in the process of becoming ready'') non-fatal. Retry the operation until it will eventually either yield a real error condition, or finally succeed. Devices like CD changers or tape drives with a freshly inserted cartridge should benefit from this. Should go into 2.2 after some testing in -current. I'd like to see this in the release if possible.
