I have a couple of USB wifi dongles based on the Atheros AR9271 
chipset.  It looks like they work fine under Linux-libre kernel 
version 6.18.55 (from the freesh .deb repository), but 
reproducibly fail to connect (and sometimes fail even to show up 
in lsusb) under Linux-libre kernel versions 6.18.56 and 6.18.57 
(from the same source).  There is some reference in the changelog 
for 6.18.56 to something relevant to that chipset having changed, 
but I don't really understand the details.  What would be a good 
way to proceed, please?
