John Bayly, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . Please note that one
will need to install Ubuntu to test hibernate, as at this time,
hibernate does not work in a live environment. If the issue remains,
could you please run the following command from a Terminal
(Applications-Accessories-Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux REPLACE-WITH-BUG-NUMBER
If reproducible, could you please provide the information following
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ?
If reproducible, could you also please test the latest upstream kernel
available (not the daily folder) following
https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional
upstream developers to examine 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. For
example:
kernel-fixed-upstream-v3.13-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. As well, please
remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
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.

Jul 11 10:08:58 BaylyJ4 kernel: [ 888.020009] PM: Error -12 creating
hibernation image
When hibernating, if there isn't enough free memory, the hibernate
file cannot be created (as expected), however instead of the system
reporting this and returning to the previous state, it appears to
freeze allowing no input - Ctrl + Alt + F1 doesn't give me a shell
login prompt. The machine will remain running indefinitely and has to
be power cycled. Upon restart, I am given a standard login prompt.
Expected behaviour would be that the OS returns the user to a state
where they can safely close any critical applications.
As an aside, I'm investigating why my system will not hibernate when I
have a total of 6GBi swap (2GBi + 4GBi), of which 5MBi is used, and
only 2GBi of RAM installed.
