This seems to happen when trying to read a broken device:

Mar 22 18:34:35 hostname systemd[1]: Assertion 'b' failed at ../src/basic/path-util.c:390, function path_compare(). Aborting.
Mar 22 18:34:35 hostname kernel: Buffer I/O error on dev sdb1, logical block 479653, async page read

summary:

Turns out this was already fixed upstream a few days ago: https://github.com/systemd/systemd/pull/2834 . I cherry-picked the fix.

This bug was fixed in the package systemd - 229-3ubuntu2

---------------
systemd (229-3ubuntu2) xenial; urgency=medium

  * udev.postinst: Quiesce error message if /sys/class/net/eno* does not
    exist. (LP: #1560112)
  * Fix assertion crash when processing a (broken) device without a sysfs
    path. (Closes: #819290, LP: #1560695)
  * Fix crash when shutdown is issued from a non-tty. (LP: #1553040)
  * networkd: Stay running while any non-loopback interface is up.
    (Closes: #819414)
  * udev: Don't kill peer processes if we don't run in a cgroup. This happens
    when running under/upgrading from upstart. udevd and everything
    else run in the root hierarchy on all controllers then, and the alleged
    cleanup of "our" cgroup becomes a system-wide killing spree.
    (LP: #1555237)
