It's annoying, but that's just a restriction of the chip. > I'm more concerned with "make sure we don't regress pre-pi4 with this > series" than "pi4 displays all work from the beginning" unfortuntely i can confirm this. With this patch series (using Maxime's git repo with multi_v7_defconfig) my Raspberry Pi 3 B hangs up while starting X (screen stays black, heartbeat stops, no more output at the debug UART). AFAIR v2 didn't had this issue.
