<pre>On pig-snb-2600, we started seeing intermitent failures for the test
spec@arb_texture_multisample@sample-position@4:
.../piglit/bin/arb_texture_multisample-sample-position 4 -auto -fbo
Stderr
sample 0 position incorrect (y axis): observed 0.093750, expected 0.125000
sample 1 position incorrect (y axis): observed 0.093750, expected 0.375000
sample 2 position incorrect (y axis): observed 0.093750, expected 0.625000
sample 3 position incorrect (y axis): observed 0.093750, expected 0.875000
This never happened before, but it just happened twice yesterday, 3 hours
appart, which suggests something has changed. Given that we only changed the
kernel, it is possible that this would be a kernel change that led to this
instability, but I fail to see how it could happen as this is supposed to be
fixed functions...
This is why I wrote the bug for mesa, waiting for your input!</pre>
