I had positive feedback on the patch I have provided in the PPA: Ubuntu-3.13.0-53.89 + patch:
commit 682de5f4135f3414ec87bb76ef400de1148393c8 Author: Dan Williams <email address hidden> Date: Fri May 8 15:23:55 2015 -0400 ahci: avoton port-disable reset-quirk Avoton AHCI occasionally sees drive probe timeouts at driver load time. When this happens SCR_STATUS indicates device detected, but no D2H FIS reception. Reset the internal link state machines by bouncing port-enable in the PCS register when this occurs.
