Hi Simon!

I am aware of several people using 860 drives with queued TRIM. And I haven't heard any complaints outside of the bug you referenced.
Also, I have tested both 860 2.5" Pro and 860 mSATA EVO on a few different systems in my lab without any problems. See:
https://lore.kernel.org/stable/yq1h87du82d.fsf@oracle.com/T/
I really wish we had some more data to work with :(
Lacking a proper heuristic I guess we don't have any choice to disable the feature. But that's sad news for the people who currently don't have problems since their performance will inevitably suffer.
