<pre>Even though the error is very random on SKL and I have a hard time narrowing it
down (i.e., simplify the piglit test itself), I see a pattern supporting the
"buffer overrun due to alignment violation"-theory. Every time I see a failure,
the corresponding texture update round reads the pixel-buffer-object until the
last line. I modified the test to use a region that don't require access to the
last four rows of the pixel buffer object. This seems to make the bug to
disappear.</pre>
