Strange lockup on Mini9 after suspend to RAM

[Morgan Gangwere]

I'm running into a strange problem during resume on a Dell mini 9 (inspiron 910) when
running F19. After coming from Debian and having a flawless suspend, this seems strange.

I have removed the @gnome group and added @xfce

Process:
 * Suspend to RAM
 * Resume from RAM
 * Xscreensaver hangs for about a minute, then pops out an authentication prompt.
 * System is slow and sluggish -- Networking is disabled and lots of things seem broken.
 * attempt to look at dmesg to see if something is wrong
 * dmesg spits out nothing related to suspend/resume
 * Check journald, which hangs and
  - Segfaults,
  - exits 0,
  - or responds that D-Bus is gone and it doesnt know what happened.
 * Attempt to restart
  - calling 'halt' immediately fails
  - calling 'shutdown -h 0' never does anything (took 1 hour to respond that D-Bus
had gone away.
  - magic SysReq doesn't work (USB keyboard)
  - Sometimes if X is running, I get punted back to a broken login prompt in Lightdm
 * Kill power and hard restart.

Attached is journald recording the failure.
