I built a Trusty test kernel with a cherry pick of commit 2a13772. Can you give this kernel a test and see if it resolves this bug? If so, we can submit an SRU request until the fix comes from upstream.
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1363462/ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1363462 Title: Crucial M550 1TB SSD missing from NCQ TRIM blacklist Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: In Progress Bug description: I own a Crucial/Micron M550 1TB SSD which does has data loss when using NCQ TRIM. The current Ubuntu Trusty kernel has a blacklist which matches all M550 SSDs except the 1024 GB (1 TB) version because the matching pattern is limited to 3 digits for size. Upstream Linux has fixed this bug already: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a13772a144d2956a7fedd18685921d0a9b8b783 Please try to get this merged and tell me where I can start an installation with a fixed kernel so I won't have a corrupt disk already on the end of the installation.
