It was then ignored. Would it help if bugs blocking testing on linux-next were Cc'ed to linux-next@vger.kernel.org, so that Stephen could investigate? FWIW, the issue of "syzbot report sent and ignored for months/years" is actually a much broader one which applies to all bugs, not just build / test breakages. There are tons of open bugs on https://syzkaller.appspot.com/upstream which are definitely still valid (sort by "Last" occurred). Long-term, to fix this we really need syzbot to start sending reminders. But first there's work needed to make the noise level low enough so that people don't just tune them out. - Eric
