Description Mathieu Dubois-Briand 2026-06-30 08:59:15 UTC 
We got this failure on the autobuilder:

Traceback (most recent call last):
  File "/srv/pokybuild/yocto-worker/meta-intel/yocto-autobuilder-helper/scripts/summarize_top_output.py", line 181, in <module>

IndexError: list index out of range

We might want to add some exception catching / traces if it does reproduce. But this file hasn't really changed since it was introduced in 2021.

It might be time to remove some of the autobuilder intermittent analysis code.
