Great, thanks. We've done some investigation into the current status of Wheezy on Hyper-V, and as of 3.2.0-2, there's about a five patch differential between linux-next and the 3.2.0-2 kernel. How can I update to the 3.2.15-1 kernel? I installed Wheezy using the latest testing ISO, but apt-get doesn't want to show a new kernel.

I'm going to sync with my developers to see if we can get a patch created - but in the meantime I'll open a bug.
Thanks!
