Maybe duplicate of those?
If you think no, then please try to reproduce the error using drm-tip
(<a href="https://cgit.freedesktop.org/drm-tip">https://cgit.freedesktop.org/drm-tip</a>) and kernel parameters drm.debug=0x1e
log_buf_len=4M, and if the problem persists attach the full dmesg from boot.
