At 10.0 no UEFI in site, network worked fine once I convinced it it was a hostname and hosts based lookup, although i do seem to recall blowing away dchpdc5 or something, what ever it was that insisted my route came from agahi. Once that was done it did everything I asked it to do for about a month, with zero hiccups until I had to get my heart rebuilt ( new aortic valve and a bunch of stents, and the lathe running as I had to make something that was bigger than my 7x12 could handle well. > [1] https://github.com/pftf/RPi4 > [2] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=950578 Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
