Blacklisted WiFi/BT drivers for balenaFin are still loaded #1395

Closed majorz closed 5 years ago

majorz commented 5 years ago

We disable the in-kernel WiFi/BT Marvell drivers in favor of the proprietary ones, but those are still loaded although they are blacklisted.

Marking it as invalid as I could not reproduce this now as well on two different OS versions, and one is prod, the other - dev.
