It looks to me like if both armsoc and modesetting are trying to use the same
GPU, acting like there are two separate GPUs. The modesetting fails to call
drmSetMaster on it, maybe because armsoc already did that first.
You could try if it gets better by disabling additonal GPUs by adding a
configuration file like this (or appending it to your /etc/X11/xorg.conf file
if you have):
Option "AutoAddGPU" "False"
