<pre>HD6450 (CAICOS), kernel 3.7.7-201.fc18.x86_64
The PC quickly locks up while playing either WoW or Minecraft 1.4.7 with Mesa
from git. However, I have an earlier version of Mesa-git that plays both games
correctly. The mouse cursor continues to move after the freeze, but the
keyboard no longer responds.
The HEAD for my working Mesa is:
commit 0e2f26d5ea26febd16173aa8bbf7427b090e320f
Author: Ian Romanick <<a href="mailto:ian.d.romanick@intel.com">ian.d.romanick@intel.com</a>>
Date: Fri Feb 8 18:03:33 2013 -0800
intel: Do not expose OES_compressed_ETC1_RGB8_texture or
ARB_texture_rgb10_a
Older hardware cannot do ARB_texture_rgb10_a2ui, and the translation
code for OES_compressed_ETC1_RGB8_texture was never implemented in the
i915 driver.
I will try and bisect this issue when I have more time with the affected PC.
Note that this issue does not happen with either my HD4670 or HD4890.</pre>
