We have figured out what is going on here. The problem seems to be

Hi Halil,

I'll send a patch shortly to fix this issue.  Sorry about the delay as I
was busy with KVM Forum and all that. :(

Hi Paolo!

With some guidance I could cook up a patch myself. But if you prefer to
do it yourself, I will be glad to test the fix (please put me on cc).
Thanks!

NP, the patch already existed but I was busy and didn't send it out.

Paolo
