The LLM actually runs scripts/decode_stacktrace.sh. The non-deterministic part
is being able to get our hands on various debug symbols from
distros/vendors/etc.

Instead of just crapping on everything, can you propose a different
deterministic solution that would have worked for
https://lore.kernel.org/all/DGRCO9SL0T5U.JTINSHJQ9KPK@imlonghao.com/ ? Or
should we just let that bug report rot as it usually happens because you have
some dislike for LLMs?
