Comment 6 for bug 1672441

I ran into this with the ISO 20170412 spin on both
 - amd64 on a Dell Latitude E6420: Intel i5 2540M + Intel Sandybridge Mobile graphics and
 - i386 on a Dell Latitude D630: Intel Core 2 Duo + Intel 965GM graphicsc

Did not catch it on my desktops however, only the Dell laptops (like Dave above).
