Public bug reported:

This seems to be a bug that has regressed, I have encountered the same
issue as 2 other reports:

LP: #1349897

Running kernel: 3.13.0-46-generic

This is replicated over many compute nodes (KVM) running OpenStack.
The workaround is to disable KSM:

echo 2 > /sys/kernel/mm/ksm/run

This fixes the issue temporarily.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete
