            Bug ID: 105190
           Summary: gem_quiescent_gpu assertion fails on distribution
                    kernels
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal

         Component: IGT
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: arkadiusz.hiler@intel.com

Running any test on Fedora causes a failed assertion during gem_quiescent_gpu()
which is used in drm_open_driver* family of functions.
