Petersen" Date: Mon, 4 May 2015 12:20:29 -0400 Subject: libata: Blacklist queued TRIM on all Samsung 800-series MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: "Martin K. Petersen" commit 9a9324d3969678d44b330e1230ad2c8ae67acf81 upstream. The queued TRIM problems appear to be generic to Samsung's firmware and not tied to a particular model. A recent update to the 840 EVO firmware introduced the same issue as we saw on 850 Pro. Blacklist queued TRIM on all 800-series drives while we work this issue with Samsung.
