dmesg output
While playing L4D2 today I got a lot of GPU lockups.
While the lockups seem to happen randomly, they are fairly easy to reproduce in
the third chapter (The Mall) of the Dead Center campaign. I recorded an
apitrace while encountering 3 lockups and there seem to be at least a couple of
lockups each time I retrace it:
<a href="http://constexpr.org/tmp/L4D2-radeonsi.trace.xz">http://constexpr.org/tmp/L4D2-radeonsi.trace.xz</a> (507 MiB)
At least driver was able to successfully reset the GPU each time.
There also seem to be some infrequent rendering glitches.

The above logs and apitrace were recorded with unsafe-fp-math enbled (see <a class="bz_bug_link

VM fault messages in dmesg while running L4D2 without unsafe-fp-math.</pre>
