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.
Thanks!

Really sorry for this false report. There was an environment issue in
the bot and caused a wrong bisection. We are working on fixing it.
Sorry again for the noise.
