I'm currently recompiling the 3.16 kernel with ATA_HORKAGE_NO_NCQ_TRIM added for the the 840 EVO, derived from this patch: https://launchpadlibrarian.net/205494465/0001-libata-Disable-native- queued-TRIM-support-Reason-fw-.patch
I'll report back on if it actually works. However, it seems that ATA_HORKAGE_ZERO_AFTER_TRIM isn't defined in the 3.16 kernel (it may not appear until 3.19?). What does it do? Is it necessary for 3.16? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1449005 Title: trim does not work with Samsung 840 EVO after firmware update (EXT0DB6Q) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fstrim/+bug/1449005/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
