commit f04bd812d75d11f32d2c950a5f1abe0aed431d58 Author: Alexandru Gagniuc mr.nuke.me@gmail.com Date: Mon Jan 20 22:26:05 2014 +0100
Revert "Butterfly, Stout: Force SATA link speed to 3 Gbps"
This reverts commit 7b8952c19d8d809b7aeec629b31e1c3d66f19884.
This commit was a hack to solve potential hangs caused by SSD bugs, but the workaround limited the SATA speed of all connected drives, despite the problem being localized to one specific model. As such, this solution is a layering violation, as it makes too many assumptions about the connected hardware.
