If you remove the dtoverlay line (just tested it) and it works fine during boot (before root is mounted), it means initrd has all necessary modules to make it work, so it's not like initrd is missing something.

This is because psplash fails to open the /dev/fb0 framebuffer device, because it doesn't exist. This appears to be due to a lack of supporting kernel modules in the initrd.img (fb_sys_fops, drm, vc4, etc.) which were formerly present but are missing from the version I'm testing (pi-kernel 4.15.0-1041.44, snap rev 42). Steps to reproduce: * Flash the image to a uSD card and boot the pi with it (preferably with a serial console attached). * Note screen remains black instead of displaying the familiar "Core" text under an Ubuntu logo. * If serial console is attached, note "Error opening /dev/fb0" in the output shortly after u-boot starts the kernel; this is output from psplash failing [1] http://cdimage.ubuntu.com/ubuntu-core/18/current/ubuntu- core-18-armhf+raspi3.img.xz To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1837209/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
