The reset on suspend was to workaround the case where suspend failed and we needed a to put the GPU into a clean state to resume without the GPU having been powered down. I think the reason this helped you was because the platform was not actually getting properly powered down so the GPU was never powered off, thus on resume the GPU was in an unknown state. SO you were not actually getting proper suspend in the first place. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
