It looks like > there's some customs scripts in there (test-mainline.sh), what are they > doing? That test script is triggering the openqa job, but its running only after lava is able to login. The trace is appearing before the login prompt even, so test_mainline.sh should not matter here. The only customization done to the default ubuntu image is the initrd. Can you please try with the initrd from https://elisa-builder-00.iol.unh.edu/kernel/mainline/rpi4/initrd.gz.. I will check with another board also. -- Regards Sudip
