Micron has released an updated firmware (MU02) for M510/M550/MX100
drives to fix the issues with queued TRIM. Queued TRIM remains broken on
M500 but is working fine on later drives such as M600 and MX200.

The upstream 3.19 kernel has tweaked the blacklist to reflect the above.
This change is also in the Ubuntu 3.19.0-18.18 Vivid kernel and the
3.16.0-43.58~14.04.1 Trusty kernel.

Title:
  Crucial M550 1TB SSD missing from NCQ TRIM blacklist

Status in The Linux Kernel:
  Unknown
Status in linux package in Ubuntu:
  Incomplete

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. Thanks!
