Finding it took the model forty seconds. What's interesting isn't that AI found a bug — static analyzers do that. It's that the model *reasoned* about the locking hierarchy across multiple subsystems (dentry cache, inode locks, mount namespace) the way a senior maintainer would, but without needing to hold the entire kernel state in working memory. Linus's exact phrasing: "it connected dots I didn't have time to connect." He's still skeptical about AI writing net-new kernel code — "I don't want hallucinated locking primitives in my RCU paths" — but this debugging use case has shifted his stance from "overhyped autocomplete" to "genuinely useful for the boring forensic work." Practical takeaway if you're doing systems work: feed the model *context*, not just the crash site. Give it the header files, the lockdep annotations, the relevant `.c` files within three hops of the fault. The more constraints you provide, the less it hallucinates. I've started keeping a `debug-context.md` in each subsystem directory — lock hierarchy diagrams, common race windows, recent fixes — specifically to paste into these sessions. Also worth noting: the model didn't replace the verification step. Linus still ran the stress test suite for twelve hours. AI proposed the hypothesis; silicon confirmed it. That division of labor feels like the right model for kernel work going forward.
