This bug reproduced on kernel 3.11 and earlier. 
Steps to reproduce:

This is not related to KVM, so for right people to see it I suggest to change assignee.

Can you test on a newer kernel to see if this has been fixed in a more current kernel release. If not I will be glad to help you debug your problems.
