Are your sure you booted the system with the v3d-fix kernel? I remember
with that kernel, the glxgears at least could run without crash or
system hang, of course the v3d-fix has some other problems.

So could you please run 'uname -a' to check the kernel you are running?

And our plan is to disable this driver temporarily, we will report bug
to usptream against rpi-5.3.y, and we will look for fixes from 4.19
branch too.

Thanks,

Hui.
