The first S3 suspend after a fresh boot works fine. Thereafter, suspends simply resume again immediately. I get the following errors on my console: [ 152.697247] i915 0000:00:02.0: GEM idle failed, resume might fail [ 152.697258] pci_pm_suspend(): i915_pm_suspend+0x0/0x50 [i915] returns -11 [ 152.697262] dpm_run_callback(): pci_pm_suspend+0x0/0x140 returns -11 [ 152.697264] PM: Device 0000:00:02.0 failed to suspend async: error -11 [ 152.697306] PM: Some devices failed to suspend, or early wake event detected The issue is not limited to my normal way of doing suspend, using "pm-suspend". It also happens using the "echo mem > /sys/power/state" method. The kernel was bisected, and the result was double checked by clean compiles of the first bad commit and the immediately preceding commit. Bisect results copied below: $ git bisect good dc4be6071a24f0d2da6af8ce16c19f276ac4d7a2 is the first bad commit commit dc4be6071a24f0d2da6af8ce16c19f276ac4d7a2 Author: John Harrison <john.c.harri...@intel.com> Date: Fri May 29 17:43:39 2015 +0100 drm/i915: Add explicit request management to i915_gem_init_hw() Now that a single per ring loop is being done for all the different intialisation steps in i915_gem_init_hw(), it is possible to add proper request management as well. The last remaining issue is that the context enable call eventually ends up within *_render_state_init() and this does its own private _i915_add_request() call. This patch adds explicit request creation and submission to the top level loop and removes the add_request() from deep within the sub-functions. v2: Updated for removal of batch_obj from add_request call in previous patch.
