The bugzilla ticket has the details; it's sadly all a bit mess (it was afaics actually a gentoo user that confirmed the above in a downstream bug tracker [https://bugs.gentoo.org/918128#c21] and a gentoo kernel dev forwarded the result to our bugzilla...). 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.
