Subject[REGRESSION] drm/amd/dc: Add dc display driver (v2)
Date
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
