Comment 3 for bug 1744511

17.04 did not have any problems, I never had 16.04 on this computer.

An update to the kernel yesterday seems to have resolved this issue (linux-image-4.13.0-31). So it's not worth investigating further at this point in time.

However, the kernel update seems to have introduced a full system freeze that occurs less often than the original problem, but this is another matter. I think I'll just run 17.04 until 18.04 comes out.

I'm not sure if this should be marked invalid or fixed, so I'll leave that to someone else.
