If anyone has any objections, please let me know. ------------------ 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.
