trace-cmd report run after the problem occurred.

Running Fedora 18, I updated on Feb 25 and started noticing that new windows
were completely black after a few hours of use.  I generally first notice it
from tooltips, menus, or other popup windows, but quitting firefox and
restarting results in a fully black window once I hit the bug.  I am using 

xorg-x11-drv-intel-2.21.2-1.fc18.x86_64 <--- buggy

but when I downgraded to:

xorg-x11-drv-intel-2.20.14-1.fc18.x86_64

everything seems to work just fine for as many hours as I have tried (probably
2-3 days iirc).  fwiw, I did downgrade some KDE packages and some other X
packages (not mesa btw, X server and X server common iirc) that were updated on
Feb 25, but was able to narrow it down to the driver.

In #intel-gfx IRC, ickle asked that I do a 'trace-cmd record -e i915' until it
failed, then a 'trace-cmd report', which is attached (it was only 15 minutes or
something after I started the record that it failed -- it was due as I had put
in 3 hours or so earlier in the day).  Also attached is my Xorg.0.log from that
run ...
