Unfortunately, the environment in which happened what I described below has certain restrictions that don't allow me to try a newer kernel than the newest that is in the standard Ubuntu repositories... So, in my humble opinion, we will just have to wait for the 5.16 to appear in the standard Ubuntu repositories. Thank you again. Very much.

I would suggest going and getting support from those that are imposing those odd restrictions on you, as they are not allowing you to use the hardware you need to use :( Good luck! greg k-h ^ permalink raw reply [flat|nested] 5+ messages in thread
