The patches to fix module signing are not in this build but the rest of the update with CVE fixes and an NFS fix seems to be okay so I'd rather push this since it's not actually a new regression. The module signing fixes will be in the 5.0.10 update which should be out Friday.
The dracut crash is interesting because based on https://bugzilla.redhat.com/show_bug.cgi?id=1685932 it's not an issue with the 5.0.x kernel itself but just installing it. This is the 4.x -> 5.x bump so I don't know if there's something there or it's just an underlying dracut issue that's being exposed now.
4.15.12 is out today so I'm going to push that as an update and obsolete this update. If you are having booting problems please file a bugzilla with system information. "It doesn't boot" with no information makes it difficult to narrow down the problem when many people do seem to be able to boot successfully.
