Linus Torvalds credits an AI with 'much of the grunt-work' in a kernel commit, and says it kept telling him the bug was unsolvable

Torvalds landed drm/xe: Don't hand out the flat CCS storage as usable VRAM on August 22 with a commit message calling it "a debug session from hell, enormously helped by an AI doing much of the grunt-work." He notes the model repeatedly stated flat out that the problem was impossible, but kept adding diagnostic code when pushed, and jokes that his own stubbornness exceeded the AI's training. The practical signal for anyone running coding agents: the failure mode is premature give-up, not wrong answers, and pushing past a confident refusal is part of the operator's job.
