As Linus has indicated in: https://lore.kernel.org/stable/CAHk-=whGd0dfaJNiWSR60HH5iwxqhUZPDWgHCQd446gH2Wu0yQ@mail.gmail.com/ the problem is the missing commit b23decf8ac91 ("sched: Initialize idle tasks only once"). Applying that on top of 6.12.2 fixes the problem. We just encountered this issue in Gentoo as well when releasing a new kernel and adding that patch has resolved the issue. > Thought it best to share before I start to work on bisect. config and > dmesg outputs attached. No need to, just add b23decf8ac91 :) cheers Holger
