I've been using an RPI4B with 4GB as my main term for several months. It pxe boots (no SD card) and I leave the session on, but run screenlock to guard against cat walk (pun?). It has rebooted once, but I'm pretty sure it was due to power fluctuations (didn't see it happen). I built the kernel on May 31st, with the latest patches at the time.

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.

Is this lightning bolt a hardware feature? Like, it overlays it on the display,
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?
