I have looked at some of that, seems stuck on arm64. Pass the salt ;o) I'm about halfway thru building a 5.16.2-rt19 kernel7l right now on the rpi4. Maybe that will work. That is about as bleeding edge as can be built right now. But I see it building modules it will never use on a pi. So I need to run menuconfig and turn a bunch of that stuff off. > Hope this helps, > Andrei Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
