From 128326a10c8d098d82af6a5d1c903dbe4b041ff4 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 27 Feb 2018 21:18:16 +0000 Subject: drm/i915: Repeat the GEM_BUG_ON message in the ftrace log As the ftrace log is overflowing the pstore capture, we lose the last gasps from dmesg which includes the GEM_BUG_ON function:line and condition that failed. Vital information for tracking down the bug, so append it to the frace log as well.
