dmesg with GPU lock-up

Commenting the old heaven profiles from ~/.drirc didn't help. Or maybe it did
change the behavior somewhat.

Attached is the relevant fragment of kern.log. The GPU did restart a few times
but eventually the system locked-up.

What's more, when the freeze happened the loading screen was displayed. So the
problem happened even earlier then before. It might have happened that way by
chance though.
