@dholbert: your lockup looks like https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1680904 (and the upstream bug is https://bugs.freedesktop.org/show_bug.cgi?id=100516). It's a bug in the Intel graphics drivers that unfortunately is present in both kernels 4.10 and 4.11, but should be fixed in 4.12.
