Thanks for your report! However, I'm afraid there's not much that we can do about it: There is no useful stack trace at all, no duplicates on Launchpad or https://errors.ubuntu.com/?package=systemd&period=month

Looks like it crashed somewhere between libkmod and glibc, even before udev started. If you see this again, please try to submit the crash again so that we can have another attempt at retracing it.

Oh, in fact bug 1228739 looks similar.
