ata: libata-core: Disable READ LOG DMA EXT for Samsung 840 EVOs
[ Upstream commit 5399752299396a3c9df6617f4b3c907d7aa4ded8 ] Samsung' 840 EVO with the latest firmware (EXT0DB6Q) locks up with the a message: "READ LOG DMA EXT failed, trying PIO" during boot. Initially this was discovered because it caused a crash with the sata_dwc_460ex controller on a WD MyBook Live DUO. The reporter "Tice Rex" which has the unique opportunity that he has two Samsung 840 EVO SSD! One with the older firmware "EXT0BB0Q" which booted fine and didn't expose "READ LOG DMA EXT". But the newer/latest firmware "EXT0DB6Q" caused the headaches.
