There was a report of silent data corruption on Fedora 20 w/ the v3.12 kernel. After some analysis of SATA traces, it appears that in certain queued scenarios, the Micron M500 SSD will exhibit incorrect protocol behavior. A support request was sent to the vendor, and a firmware fix is in the works. Until a firmware update is deployed for the Micron/Crucial M500 SSD, the ATA driver should avoid issuing the queued TRIM commands to the affected devices. This patchset adds a new horkage flag to let the queued trim commands be disabled, depending on the drive model string.
