Comment(by dwmw2):

 None of the debug logs here help me much, because they are done without
 turning on libertas debugging. Please, when capturing kernel logs, {{{echo
 0x186184 > /sys/module/libertas/parameters/libertas_debug}}} first.

 With a relatively recent driver including many of my cleanups, and a
 5.110.20.p47 firmware, Richard has observed the firmware get into a state
 where it returns the result '4' to every command we send...
