Linus Torvalds credits AI with grunt-work on kernel debug session

Linux kernel creator Linus Torvalds credited an AI assistant with performing much of the analytical work during a difficult graphics driver debug session, according to a quote collected by Simon Willison on 22nd August 2026. Torvalds even allowed the AI to write the commit message for the resulting patch - a drm/xe: Don't hand out the flat CCS storage as usable VRAM fix in the Linux kernel.

His account of the session was not entirely flattering. The AI, he wrote, several times stated flat out that this was impossible and unsolvable and that we should just write a report about it. Torvalds pushed through that resistance each time, and the model continued adding debug code and analysing results when instructed to do so. His dry verdict: I suspect those things have been trained by people who may not be quite as stubborn as I am.

Despite the friction, Torvalds acknowledged the tool’s value in handling repetitive diagnostic work - what he called much of the grunt-work - and signed off with a direct acknowledgment: credit where credit is due.

The episode illustrates a pattern that practitioners encounter regularly. Current AI coding assistants can be effective at systematic, iterative tasks - running debug cycles, instrumenting code, parsing output - yet they tend to surface premature conclusions when a problem resists easy resolution. The practical takeaway is that an AI’s declaration of impossibility is a signal to push harder, not to stop. Torvalds’s session suggests that treating the model as a persistent but somewhat risk-averse collaborator, rather than an oracle, extracts more value from it: supply the stubbornness yourself and let the tool handle the repetition.
