--- Comment #20 from MirceaKitsune <sonichedgehog_hyperblast00@yahoo.com> ---
For the time being, I've decided to test whether this also happens with the
RadeonSI scheduler. To make sure I'm applying it to all games across the
system, I've added the following line to ~/.profile and restarted:

export R600_DEBUG=sisched

I managed to play Minecraft for over an hour several times, including in areas
with many mobs and therefore skeletal models in view... so far no freeze.
However it will take much more testing to be sure this makes a difference, so
far there is no real verdict. I'll also follow the advice of testing with
Supertux Kart, which should be an easier test case for other developers.

If the SI scheduler does turn out to fix the problem, it would mean this is a
bug specific to the old scheduler (still default, hence why that environment
variable is needed to switch). That would make sense since IIRC the scheduler
influences how drawable items are queued and rendered, which is a likely
candidate for something causing an error that freezes the system.
