Description Mark Janes 2015-09-24 20:37:46 UTC 
one of Mesa's g965 continuous integration systems encounters occasional GPU hang on this piglit test.

 [drm] stuck on render ring
 [drm] GPU HANG: ecode 4:0:0xfde5fafd, in fbo-maxsize [8834], reason: Ring hung, action: reset

Running the test suite with i915.reset=0, this test was found to be running in several of the hang cases.

Strangely, otc-gfxtest-g965-02 encounters the hang, but otc-gfxtest-g965-01 does not.  The failing system is a mobile:

jenkins@otc-gfxtest-g965-02:/$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)


in contrast, the working system is a desktop:
jenkins@otc-gfxtest-g965-01:/$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02)
