Comment 14 for bug 1751268

Narrowed down the possibilities: just fished the 4.16.0-rc7 rpms for f28 out of koji: same crash, same lack of any entries into /var/log/messages whilst doing so. So, the problem isn't fixed in the newer kernel: it them must be something that's in the Fedora kernel and not in the drm-tip kernel.

Ideas for how to narrow this down?
