Thank you Ben!

I'd like to give that kernel one a try on real Hyper-V with a fresh
wheezy and report back
just to make sure if you don't mind.

Finally we should decide on which of the patches we could itegrate for
the ata_piix vs. hv_storvsc
precedence - be it the Ubuntu or the Suse patch.

Ben: Do you have a preference on which one of the patches fits into
wheezy's kernel?

I prefer that this is resolved upstream.

Ben.
