Btw you will need a recent raspberrypi-firmware (iirc since 10/2018), too. For reference I was using 1ea8781 from 18/12/2018, I noticed there's a new one that fixes colour issues with the cameres. Given I couldn't work out exactly which random patch set I had for the test kernel I've now moved to a 4.20.1 with cacheline and this patch series. I still get the same series of crash there from just running qv4l2. I get a blank OpenGL window (could be something unrelated with the vc4 driver), and the same issue with cheese.
