Are you using > an "official" pi4 power supply (5.2v)? Yes; same power supply on the 4GB and 1GB models. That is, same exact unit, on the same outlet. I had all sorts of problems with my first several= Pi and know better than to mess around with that now. > The pi4 flashes the red power LED to indicate undervoltage, so you can lo= ok > out for that if you don't have a monitor to see the lightning bolt on. Is this lightning bolt a hardware feature? Like, it overlays it on the disp= lay, even on Plan 9? I've never seen it. I'll watch for the power LED indicator. I've also got the bad behavior on two different 1GB models, so it's at least pretty unlikely to be a hardware issue. Then this went other places. Is anyone else running a 4GB Pi 4 with Richard= 's latest kernel, successfully? Terminal or cpu? ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Te91377223453b8c0-M1b624= ba300accbe1272f6cbd Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
