Bug ID: 92108
Summary: [g965] intermittent gpu hang on
piglit.spec.ext_framebuffer_object.fbo-maxsize
Product: Mesa
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i965
Assignee: idr at freedesktop.org
Reporter: mark.a.janes at intel.com
QA Contact: intel-3d-bugs at lists.freedesktop.org
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 at 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 at otc-gfxtest-g965-01:/$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated
Graphics Controller (rev 02)
