I can not start neither gnome-shell(wayland) nor weston (I have never tried to run X on this board don't know if it's broken too or not) after recent mesa package upgrade on my raspberry pi model 2B running ArchLinux Arm. Both compositors failing with segfault inside the vc4_dri.so
I have played with apitrace and gdb to gather information which I hope might be helpful for investigation.
System details:
[alarm@alarmpi ~]$ pacman -Qo /usr/lib/dri/vc4_dri.so
/usr/lib/dri/vc4_dri.so is owned by mesa 18.3.1-1

Same problem with rpi 3 here, could be related to this.
ZakMcKrack3n commented
Can you update to 18.3.3 and check again ? Did fix it for me.
VestniK commented
I don't have spare time to play with my raspberry pi this week. I'll try to update mesa next week and write the results here. Looks like my issue is the one described in the article from the link.

I've tried to update mesa and run gnom-shell --wayland. Mesa 18.3.3 works fine.
