can you produce this with latest kernel (drm-tip branch)? This looks like a bit
older than the latest kernel.
(https://cgit.freedesktop.org/drm-tip).
If problem exists with latest drm-tip, set kernel parameters drm.debug=0x1e
log_buf_len=4M and reboot.
Try to reproduce the issue and attach the dmesg log. This way we see more
information about the bug.

This information is needed for debugging this issue.
