I don't think it is nessessarry to install the mainline kernel at this point. The latest 3.11-rc5 kernel does not have your system blacklisted in the Intel IPS code.
The kernel I mentioned in comment #6 blacklists your machine in the IPS code. It sounds like it stops these messages from spamming your log, per comment #13. I will submit this patch upstream and to the Ubuntu kernel team mailing list.
You also mentioned the system still does not shut down. That is probably a separate bug. Can you open a new bug for that issue?
