From f468980171fa6293917a8b59bfec71c6616e06c9 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 9 Oct 2013 19:22:22 +0200 Subject: [PATCH] drm/i915: Educate users in dmesg about reporting gpu hangs Untangling me-too reports that actually aren't is really messy. And we need to make sure the blame is put where it should be right from the start ;-) v2: Improve the wording from Ben's suggestions.
