Various consumer NVMe's use 3rd party controllers, so maybe that's the
common denominator. There aren't very many to choose from.

Anyway, the suggestion won't fix random IO stalls when the situation
happens, but if it is successful, it should keep the volume in an
optimal state, albeit with exceptionally high latency during the
recovery window.
