Please do not add long logs as comments. They make the bug reports difficult to
navigate. Please use the "Add an attachment" link near the top instead, and add
plain text attachments.

Please add drm.debug=14 module parameter, and attach the dmesg all the way from
boot to the problem again.

> [    0.402053] [drm] radeon kernel modesetting enabled.

Is this reproducible with radeon disabled?

Please always attach the crash dump for GPU hangs as indicated in the dmesg.
