[PATCH] Prevent interface errors with Seagate FreeAgent GoFlex

From: Daniel J Blueman
Date: Thu May 03 2012 - 11:21:28 EST


When connected by the optional eSATAp cable, various interface errors
occur with my new external Seagate FreeAgent GoFlex (firmware 0110) until
the interface is forced to 1.5Gbps mode. Blacklist 3.0Gbps mode with it
to avoid the error messages, delays and dataloss potential.
