I'm taken a bit back and forth here and it seems we are stuck again. So let me try again to hopefully clear things up a bit: André, could you please state * What practical use-case actually stopped working? * What Linux kernel version actually worked for your (because if thing broke when you upgraded from a vendor kernel to a vanilla kernel than this does not qualify as regression IMHO) 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.
