Nothing else happens, no messages on the console. In both cases I'm building core-image-full-cmdline, and the only tweak in local.conf is: ENABLE_SPI_BUS = "1" As far as I can tell, the only difference between the two raspberry pi layers is the kernel. Andrei's uses 4.1 and Khem is using 4.4: $ git show-branch kraj/master origin/master * [kraj/master] userland: Fix tearing effect seen with wayland compositors !

Unless someone else has better-sounding ideas? Best regards, Trevor
