According to them queued trim support is broke on the drive. I also experienced this on an 840 Pro and now I have the same issue on an 850 Pro. It's my understanding we have to wait on a fix from Samsung, so maybe someone at Canonical knows how to get a hold of Samsung to let them know that queued trim support is broken on their SSDs in Linux... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1338706 Title: Samsung SSD 840 failed to get NCQ Send/Recv Log Emask 0x1 failed to set xfermode (err_mask=0x40) on upstream kernels >= 3.12 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1338706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
