Created attachment 97210 [details] System random hung System Environment: -------------------------- Platform: ILK SNB IVB HSW BYT BDW kernel: (drm-intel-nightly)35dc7c8af75a3e5ae52a5469786602ce083a6368 Bug detailed description: ---------------------------- System random hung while run some subcases of gem_reset_stats, like close-pending-fork-render, ban-vebox etc. The hung rate about 1 out of 6. Reproduce steps: ---------------------------- 1. ./kms_flip --run-subtest close-pending-fork-render
Please retest with latest drm-intel-fixes: commit 691e6415c891b8b2b082a120b896b443531c4d45 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Apr 9 09:07:36 2014 +0100 drm/i915: Always use kref tracking for all contexts. Might be related to bug #74100 but unlikely.
Adding Mika for more clue.
Checked on latest -fixes(b6842feb63a23a6a988f4e1ffb93408d8ff6931e), this bug still able to reproduce. Make correction Reproduce steps: ---------------------------- ./gem_reset_stats --run-subtest close-pending-fork-render

But I found a error on ILK platform. the error information shows blow. Thanks.

It's system hung, only found on HSW ULT. ./gem_reset_stats --run-subtest close-pending-fork-render failure didn't reproduce on latest -nightly(dd28119c31cf06fc4c3bb548699018a91e45a676).

Only on HSW ULT? Are all the other platforms mentioned in the bug headline now solid?
