That's a nice understanding, but I believe it's an incorrect one: # echo 'options rtw88_pci doesnotexist=helloworld' >> /etc/modprobe.d/rtw.conf # modprobe rtw88_pci; echo $? 0 In fact, while I was already quite aware about the removal Jakub is highlighting (in the rtw88 driver), I was a user of the parameter, and was quite happy to see it die (because now the driver does the Right Thing automatically). I still left the option in my modprobe.conf, while I finished staging upgrades of all my systems. I ran into no problems, and now that the migration is done, I killed the modprobe.conf entry. Brian
