Hi Luigi,

Sorry for really really late response.
Today I have a time to look at this problem and it seems to found the problem.
By your help, I can reprocude this problem easily on my KVM machine and this
patch solves the problem.

Could you test below patch? Although this patch is based on recent mmotm,
I guess you can apply it easily to 3.4.
