Mark Bohn, thank you for reporting this and helping make Ubuntu better.
Could you please test the latest upstream kernel available from the very
top line at the top of the page (the release names are irrelevant for
testing, and please do not test the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc7

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Linux silpion 3.13.0-40-generic #69-Ubuntu SMP Thu Nov 13 17:53:56 UTC
  2014 x86_64 x86_64 x86_64 GNU/Linux

  Fresh install - ssh, Samba, Postfix

  Most times (but not all), when attempting to reboot, the system hangs with the following message:

  I have done 3 clean installs on 3 identical PCs, all with the same
  result.
