Description Eric Appleman 2011-03-02 14:51:59 UTC
Noticed on both Ubuntu 10.10 and Fedora 14. Ubuntu 10.04 is not affected.

Reference bug with relevant log files: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/718019
Comment 1 Chris Wilson 2011-03-02 15:12:04 UTC
Distinct lack of information. I note that upstream still works on my 915GM,  945GME, PineView and Q35.

Grab rendercheck and attach its output.
Comment 2 Eric Appleman 2011-03-02 15:56:46 UTC
Rendercheck chokes when it reaches the a8 composite mask test. I let it sit for 10 minutes and nothing happens.

All preceding tests seem to run just fine.

Is it possible to get a partial output?
Comment 3 Eric Appleman 2011-03-02 16:06:02 UTC
btw, above is on latest stable bits. i can repeat with latest unstable bits if you'd like.

i believe it's worth stressing that render-bench and jxrendermark fail outright with the latest stable bits on live and installed sessions.

Just a slow machine. The full test run will take over a day...

However, it runs unlike your earlier tests. And if it reports no rendering errors, my suspicion rests with your libraries or test binaries.

If you can pinpoint the error within the driver, then please do reopen with the evidence of the smoking gun. Until then, I remain convinced that the problem lies elsewhere.
