The err field indicates the controller thinks the device disconnected
and then reconnected.  Possibly the firmware on the ssd was resetting
itself (or something similar).

Can you see if a more recent firmware version is available for your
SSD?  Otherwise, it looks like this could be worked around in SeaBIOS,
but it wouldn't be particularly nice.
