Bisect failed: http://build.chromium.org/p/tryserver.chromium.perf/builders/android_nexus5X_perf_bisect/builds/693
Failure reason: the build has failed.
Additional errors:
Either of the initial "good" or "bad" revisions failed to be tested or built.

re-kicking a bisect. If this fails, I'll CC the test owners for recommended next steps.

Status: Untriaged (was: Assigned)
Status: WontFix (was: Untriaged)
This alert was found before M-60 branched. Closing as WontFix as this is believed to either be invalid or non-reproducible.
