From 7d1da805838186a88316ef3b08df458b1acd6296 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Thu, 4 Dec 2014 13:13:28 -0500 Subject: ahci: disable MSI on SAMSUNG 0xa800 SSD commit 2b21ef0aae65f22f5ba86b13c4588f6f0c2dbefb upstream. Just like 0x1600 which got blacklisted by 66a7cbc303f4 ("ahci: disable MSI instead of NCQ on Samsung pci-e SSDs on macbooks"), 0xa800 chokes on NCQ commands if MSI is enabled. Disable MSI.
