Subject: [PATCH 0/2] libata: disable queued trim for Micron M500 SSDs
Date: Mon, 16 Dec 2013 18:15:52 -0800 [thread overview]
Message-ID: <1387246554-7311-1-git-send-email-marc.ceeeee@gmail.com> (raw)
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.
