No, that was with the normal upstream component testing which doesn't patch
anything (any applied patches would get soon stale and fail automated builds),
to see whether minor gfx stack differences affect the hangs (and they didn't).

I added it so that you can check whether additional hangs (with latest,
unpatched Mesa) are also for the same reason.

With the patch I wasn't able to reproduce hangs (within 21 rounds, whereas
unpatched tests got one hang within 12 rounds, so it looks good).
