Subject: [PATCH] ahci: disable MSI on SAMSUNG 0xa800 SSD
Date: Thu, 4 Dec 2014 13:19:59 -0500 [thread overview]

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.
