And this was a debug session from hell, enormously helped by an AI doing much of the grunt-work.
I’d like to call it my tireless helper, but the AI several times stated flat out that this was impossible and unsolvable and that we should just write a report about it.
I suspect those things have been trained by people who may not be quite as stubborn as I am.
But while the AI was ready to give up several times, it did keep adding debug code and analyzing it faithfully when I pushed. So credit where credit is due and I let the AI write the commit message above.
This is basically a one-liner fixing a bogus
`round_up()`
to a`round_down()`
, but there were 24 patches adding more and more debug information to this, and 18 kernel boot to finally narrow it down to this. — Linus
Linus Torvalds, in the commit message for a kernel fix.
I troubleshoot every now and then myself, and it’s way harder than programming, tbh. AI can’t always find the root cause. But it’s still a tireless companion to have on-call — it surfaces details I’d have missed on my own, and some of them are the ones that end up pointing the way.
