Add kernel debug trace to Invalid IPC Message Errors
Add kernel debug trace to Invalid IPC Message Errors

  - There is an extremly intermittent situation
    where on a system with no IPC message passing
    the INTRP will receive an IPC message from the
    kernel. To debug why this is happening, the
    printk buffer is being added to the errorlog to
    help debug this problem the next time it occurs
