Greetings. I'm also getting a GPU crash / system lockup, when running Minecraft
as well as other game engines. It doesn't happen during the splash screen, but
probabilistically while the game is running. The problem was introduced at the
same date as the making of this report, also around the time my distribution
upgraded to Mesa 17.1.

I assume I'm experiencing the same bug described here, since I honestly don't
see Mesa 17.1 introducing two completely unrelated crashes that would cause a
renderer as simple as Minecraft to crash the OS. However I updated to Mesa
17.1.4, and surprisingly it still occurs.

Therefore it's possible that this was not fixed. Since it's not my bug and I
don't wish to inconvenience folks, I won't set the status to reopened...
however the developers might wish to take a look at this. Here is my own
report:
