I was not aware at all of the modesetting driver... perhaps it'd be good to document somewhere, like maybe the pkg-message for drm-kmod? > Are you running SNA or EXA? xorg.0.log might provide some useful > information. I don't know what SNA or EXA are. I'll report back if I get another hang with the modesetting driver. It can take a while to shake out.
