Ben Kahle, as per http://www.dell.com/support/home/us/en/04/product-support/product/latitude-e6420/drivers an update to your BIOS is available (A21). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything?  If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

Title:
  [Dell Latitude E6420] Occasional Lock-up on Suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to Ubuntu 14.04 my computer will no longer suspend
  consistently. Approximately 20% of the times I suspend from the menu
  or command line, the screen will go black and display the following
  text. The only way to gain control at this point is to hard reset the
  computer.

  [ 445.032801] PM: Syncing filesystems … done.
  [ 445.057818] PM: Preparing system for mem sleep
  [ 445.058006] Freezing user space processes --- (elapsed 0.001 seconds) done.
  [ 445.059860] Freezing remaining freezable tasks … (elapsed 0.001 seconds) done.
  [ 445.061194] PM: Entering mem sleep
  [ 445.061247] Suspending console(s) (use no_console_suspend to debug)
