I initially thought my machine was failing to boot entirely, but it

I suspect the culprit is the rockchip_vpu driver (in staging/media),
which has been renamed to hantro in this merge window. When I run startx
from a terminal, X fails to start and Xorg segfaults (log here:
http://users.sussex.ac.uk/~ad374/xorg.log). X seems to work without any
issues in v5.1.
5.2 also has support for Panfrost (Mali-Midgard GPUs) but I'm not
sure if it already can support X11 yet and your X11 log mentions
libglamoregl in the segfault stack trace.
Apart from it bisect that Greg suggested you could also just try
blacklisting either panfrost or vpu kernel modules
/etc/udev/somewhere . This would prevent them from loading
Hope that helps

Hi Heiko,
Thanks for this. I blacklisted the panfrost driver and X magically
started working again.
I'll try to do a bisect later to find the offending commit though.
In related news, it also seems that the sound and wifi drivers aren't
working either in 5.2 (although I need to do a bit more testing to
confirm the latter).
Best,
Alex
