    Cool, well done on sussing it out.

    Bear in mind that you'll likely have more upgrading to do next April as 12.04 hits the end of the road

    uname -r
    4.4.0-45-generic

    Presumably this kernel does not have the bug?

    Sort of.. I believe you need to have 4.4.0-45.66 to be patched. What's the output of..

    Code:
    apt-cache policy linux-image-4.4.0-45-generic
    Code:
    apt-cache policy linux-image-4.4.0-45-generic 
    linux-image-4.4.0-45-generic:
      Installed: 4.4.0-45.66
      Candidate: 4.4.0-45.66
      Version table:
