[Bug 1363462] [NEW] Crucial M550 1TB SSD missing from NCQ TRIM blacklist
Public bug reported:
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. Thanks!
