Please attach dmesg with drm.debug=14 module parameter set. That may require some effort if the system spontaneously reboots and you can only reproduce on a live image, but there isn't much we can do without.
Timeout, closing. Please reopen if the problem persists with latest kernels.
Closing after 2 months of timeout.
