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>

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.
