This failure looks unrelated to the commit it points to. lkp@, can you have a look at your bisection rules in a bit more of detail? There are at least 2 problems with this report: 1. the commit is 1.5 years old, it's unlikely you care about that old material 2. build failure might be an indication of a flaky build failure (or outright stale build tree) Both points have a chance of decreasing signal value from 0-DAY CI.
