Roman,
My Samsung 860 EVO mSATA 500GB SSD lockups for 20-30 seconds on fstrim, while dmesg is repeatedly flooded with:
Is that specific to the mSATA model?
FWIW, queued TRIM works fine on the 2.5" form factor. So it would be best if we could limit the blacklist entry to the mSATA version (or a particular firmware rev).
