Can you please elaborate the issue? What is the scenario here? How often it
occurs? What's the platform?
Can you please attach the dmesg from boot with kernel parameters drm.debug=0x1e
log_buf_len=4M?

Have you verified the issue with drmtip? If not I would recommend to verify the
issue with drmtip (https://cgit.freedesktop.org/drm-tip).
