this bug.

I tested it with linux 3.19 and different (git~51b43c5, 10.4.6, 10.3.5) mesa
versions, but they don't seem to make a difference. So, no,
a338dc01866ce50bf7555ee8dc08491c7f63b585 does not help. Even with mesa 10.3.5,
where some people reported this was the the last working version for them, the
hangs occured. So it's probably related to some kernel issue, too.

The hangs only seem to occur ( at least surface ) on Minecraft 1.8+. Probably
because that was a bigger update and they changed the rendering code
significantly. The hangs occur every few seconds and freeze the screen for <5s.
