Hi Harry,
A kernel bug report was opened against Ubuntu [0]. After a kernel bisect, it was found the following commit introduced the bug:
commit 4562236b3bc0a28aeb6ee93b2d8a849a4c4e1c7c Author: Harry Wentland <harry.wentland@amd.com> Date: Tue Sep 12 15:58:20 2017 -0400
drm/amd/dc: Add dc display driver (v2)
The regression was introduced as of v4.15-rc1 and still exists in current mainline. The commit does not need to be reverted to resolve the bug. Disabling the CONFIG_DRM_AMD_DC_PRE_VEGA option makes the bug go away. I was hoping to get your feedback, since you are the patch author. Do you think gathering any additional data will help diagnose this issue?
Thanks,
Joe
