Created attachment 111834 [details] dmesg ==System Environment== -------------------------- Regression: Yes Non-working platforms: BDW ==kernel== -------------------------- drm-intel-next-queued/27401d126b5b1c8dd4df98bbb60b09ff2b3d5e60 ==Bug detailed description== ----------------------------- It fails at the 2nd cycle on BDW with -nightly and -queued kernel(We disabled this case in regular testing due to system lost IP after suspend,pls refer to the blacklist). Bisect shows: 27401d126b5b1c8dd4df98bbb60b09ff2b3d5e60 is the first bad commit commit 27401d126b5b1c8dd4df98bbb60b09ff2b3d5e60 Author: Thomas Daniel <thomas.daniel@intel.com> AuthorDate: Thu Dec 11 12:48:35 2014 +0000 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Mon Dec 15 11:25:28 2014 +0100 drm/i915/bdw: Enable execlists by default where supported Execlist support in the i915 driver is now considered good enough for the feature to be enabled by default on Gen8 and later and routinely tested. Adjusted i915 parameters structure initialization to reflect this and updated the comment in intel_sanitize_enable_execlists(). There's still work to do before we can let the wider massive onto it, but there's still time left before the 3.20 cutoff. v2: Update the MODULE_PARM_DESC too.
