The driver is telling you that the transfers CRC check are not valid
and it is retrying the transfer. This can be due to many things:
Bad cableing, cable too near field generating devices in the machine,
bad disk, bad controller, bad driver...
Mostly though this is due to one of the two first items.

I need a full verbose bootlog (dmesg) before I can give you any more
diagnostic on this..
