<pre>Something seems to have been broken in llvm 3.5 after svn revision 209067.
What I am experiencing is that the system is stable for desktop usage but after
a few minutes from launching a game (I have tried with CKII, Witcher 2,
Watelands 2, Cities in motion, Deadfall Adventures and Serious Sam 3) or just
after a few seconds after exiting the game the desktop freezes, the screen goes
black (can't switch to vt to kill the game/desktop session) and the system
becomes unresponsive. I'm afraid I cannot obtain a dmesg log due to that
unresponsiveness.
If a dmesg log is needed to know the system's specs, the following attachement
of another bug report may be of use:

I am using a llvm ppa to install llvm 3.5 git. I've tried to compile llvm with
no luck, so I cannot bisect. However, I still have in /var/cache/apt/archives
the deb packages for svn revisions 209564, 209581 and 209600 and those
revisions hang the system in the way described above. So judging by the R600
llvm backend activity
(<a href="https://github.com/llvm-mirror/llvm/commits/master/lib/Target/R600">https://github.com/llvm-mirror/llvm/commits/master/lib/Target/R600</a>) and my
experience with those svn .deb packages I still have in the apt cache, it seems
the culprit must be a commit after 16 May.</pre>
