I got similar problems (shutdown hanging, mount:/ is busy) with Ubuntu 14.04 on a Dell Precision WorkStation 390,
after boot ing dmesg displayed a kernel 'Oops: 0000 [#1] SMP', a few lines below the 'i82975x_edac' is listed:

I blacklisted the i82975x_edac module and voila, the machine shuts down without problems.

Title:
  pci_devices does not terminate at computer shutdown

Status in “pm-utils” package in Ubuntu:
  Confirmed

Bug description:
  I have a clean install of 13.10 using the 3.11 kernel. I have
  previously reported this bug with the 2.12 kernel (Bug #1261898), when
  I used apportcollect it instructed me to use standard Kernel and re-
  report if bug persists; it does...

  When I shutdown or restart the process hangs. I press a key and I see:

  **Killing all remaining processes ....... [fail]** (fail is in red)
  This is followed by more info (sometime referring to nm-dispatcher or modem and always ends:

  mount:/ is busy

  will now restart (or halt as the case may be)
  Then nothing else happens the process hangs there, power on my PC (Dell 5150 desktop) remains on and I need to do a "hard reset" to turn my PC off.

  I have seen relatively similar problems but none match mine exactly, I
  have attempted using:

  sudo shutdown -P now

  or

  sudo shutdown -H now

  or

  sudo reboot

  But the results are the same.
