--- Comment #7 from Robin beanow@oscp.info --- Created attachment 133098 --> https://bugs.freedesktop.org/attachment.cgi?id=133098&action=edit kern.log for drm-next-4.14-wip
Building the drm-next-4.14-wip branch including both patches does not resolve the issue and behaves similar to the previous 4.13rc2 kernel regarding ring test errors showing up. Typically 1, 9 and/or 10.
