I've just encountered this problem on a Linode guest www.linode.com. The guest is running Ubuntu 10.04 with kernel Linux s1 2.6.32-46-generic-pae #108-Ubuntu SMP Thu Apr 11 16:11:56 UTC 2013 i686 GNU/Linux
I spoke to Linode and they said it was fixed in kernel version 3.8.4 so in theory all versions of Ubuntu could be affected.
