I got this again in a VM, remembered to run 'pstree', but forgot '-a',
so I have this output which looks like it could be as suspected.

Unfortunately it didn't reproduce with a downgrade, reboot, upgrade
test so I can't get any better output right now. :(

I guess installing vivid and upgrading to wily's udev or so ought to do
it. Or if you're sure it is that other one then just dupe it.

Title:
  Upgrading udev from 220-7ubuntu2 to 221-1ubuntu2 took 60s

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  On all three of my wily systems which just got dist-upgraded to udev
  221-1ubuntu2 from 220-7ubuntu2, udev's postinst took ~60s to complete.

  The following is in the journal:

  Jun 30 09:55:40 nightingale systemd[1]: systemd-udevd.service: Watchdog timeout (limit 1min)!
  Jun 30 09:57:12 nightingale systemd[1]: systemd-udevd.service: State 'stop-sigabrt' timed out. Terminating.

  Jun 30 09:57:12 nightingale systemd[1]: systemd-udevd.service: Failed with result 'timeout'.
  Jun 30 09:57:12 nightingale systemd[1]: Starting udev Kernel Device Manager...
  Jun 30 09:57:12 nightingale systemd[1]: Started udev Kernel Device Manager.

  This is not reproducible with just a plain apt-get install --reinstall
  - could try to downgrade and upgrade again if you want.
