When a bisection apparently went sideways it's best to not bother the culprit's developers with it, they most likely will just be annoyed by it (and then they might become annoyed by regression tracking, which we need to avoid). I'd have forwarded this to the network folks, but in a style along the lines of "FYI, in case somebody has a idea or has heard about something similar and thus can help; if not, no worries, reporter is repeating the bisection". > Anyway, I'm adding this regression to be tracked in regzbot: > > #regzbot introduced: a3efabee5878b8 https://bugzilla.kernel.org/show_bug.cgi?id=217678 > #regzbot title: packet drop on Intel X710-T4L due to ipvu boot fix > > [1]: https://bugzilla.kernel.org/show_bug.cgi?id=217678 Side note for the record: Stephen also forwarded this. And let me also clear the commit you specified, as it sounds it's unlikely to be causing this. #regzbot introduced: v6.3..v6.4 #regzbot monitor: https://lore.kernel.org/all/20230717115352.79aecc71@hermes.local/ 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.
