Not sure who you mean with "they" here. Isn't the main question if André used a vanilla kernel beforehand on those Android devices and now is unable to do so? André, is that the case? Or did you only encounter this regression when switching from a patched kernel to a vanilla kernel? Also: André, do you see this in some test env, or in some real use case where others might also run into the problem? > André might want to clarify, but I've not seen any concrete real world > examples of regressions caused by this change outside of Android. Yeah, some clarification from André really would be helpful. Thx again for the answer. 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.
