As mentionned on Twitter (see discussion: https://twitter.com/warpdesign_/status/953002698550456321), Speedometer 2.0 stops at test 14 out of 180 on my phone. Nothing happens after that, the screen stays gray.
Opening the console, I could see this error (not sure it's related):
Failed to find a valid digest in the 'integrity' attribute for resource 'http://browserbench.org/Speedometer2.0/resources/todomvc/architecture-examples/emberjs/dist/assets/todomvc-5d3e8eb3d5b3740a33185edcb11eeb57.js' with computed SHA-256 integrity 'ScQsZq/r+27yytOKq12xioSwaK1J4THoK/b32e+bylE='.
