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
