Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

This makes it look like the swap process has failed. However if the swap is disabled, upstart appears to fail which is previous in the bot sequence. This is on the server version of 14.04. This error is unrecoverable as only num-lock and CTRL-ALT-DEL seem to work, no other terminal is accessible through keyboard combinations. I have wiped the partitions and reinstalled and have had a running version of the desktop (13.04) on the same drive. The terminal is accessible via SSH however. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version k3.13.0-24-generic.
