Package: linux Version: 3.16.7-ckt11-1 It was recently discovered that newer firmware versions for Samsung 8* SSDs claim to support SATA 3.2 features, but that NCQ TRIM has data corruption bugs. For this reason that feature was added to the blacklist with this commit
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drive rs/ata/libata-core.c?id=9a9324d3969678d44b330e1230ad2c8ae67acf81 Here is the ubuntu launchpad bug which has a lot of details, https://bugs.launchpad.net/ubuntu/+source/fstrim/+bug/1449005 status in debian * the 4.0.5-1 in unstable has this fix * the 3.16 in kernels in jessie and wheezy-backports do not and probably need it. * the wheezy and squeeze-backports 3.2 kernels don't have it, but I do not know if they support NCQ TRIM * I don't know the level of TRIM support in the squeeze 2.6 kernel. discard/TRIM wasn't enabled by default on squeeze/wheezy, I don't know about newer. But it's likely lots of users have enabled it. I think it probably should be backported to older kernels, maybe implemented in upstream as well. ATA_HORKAGE_NO_NCQ_TRIM workaround was first implemented 2013-12-17 (~3.12) with https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/ drivers/ata/libata-core.c?id=f78dea064c5f7de07de4912a6e5136dbc443d614 -- Matt Taggart [email protected] -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
