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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1210848 Title: Ubuntu 12.04 LTS - intel ips failed to update for more than 1s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1210848/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
