Please file a bug at
https://gitlab.freedesktop.org/drm/intel/issues/new
Boot both kernels (revert vs. no revert), passing
'drm.debug=0xe log_buf_len=4M' to the kernel cmdline,
and attach the resulting dmesg from each to the bug.
Also would be good if you try to reproduce on the
latest drm-tip (git://anongit.freedesktop.org/drm-tip drm-tip)
as well.
