I didn't have long to glance at the logs, but I am seeing the systemd segfault related to udev. This is with whatever version my F28 system had installed, not the version I compiled from GH. So, looks like an issue in the kernel. I'll try to extract more info from the journal when I get a chance. Are there any boot options, etc. that would produce additional helpful info?
