To you and everyone else that looked into this: sorry for the trouble this caused. The reporter's guess was wrong, as the reporter meanwhile confirmed in the bugzilla ticket that the problem started to happen earlier. Bagas, please be a bit more careful and don't blame a specific commit unless it's was found by bisection, a revert through a lucky guess, a statement from a developer, or something like that. In cases like this it would have been better to sent the developers of said commit a quick mail along the lines of "could you imagine that this change could lead to the problem the reporter described". But even that might be too much in a case like this, as too many of such false alarms and inquiries will make developers start hating or ignoring regression tracking in general or mails from you or me – and that is something that must be avoided, as without help from developers regression tracking becomes a lot harder or impossible. Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page. P.S.: Updating regzbot status, while at it: #regzbot introduced: v6.1..v6.2
