The bisection got nowhere.

I've tried to repro on the cubietruck on my desk and have gotten
nowhere.

But I've just now noticed that the failures are on arndale (not sure why
I thought ct).

Can I steal the arndale off your desk please?

BTW, it doesn't seem to be a 100% failure rate, e.g. 57271 seems to have
passed, despite testing the exact same thing as 57242.

Ian.
