This list is kept relatively up-to-date. Gentoo kernels are only lightly patched, and the majority of bugs have been reproduced on unpatched kernels and reported upstream. Gentoo only track release kernels, not -rc releases (it's nice to see the scope of Adrian's previous work increased).

This list is kept relatively up-to-date. Gentoo kernels are only lightly patched, and the majority of bugs have been reproduced on unpatched kernels and reported upstream. Gentoo only track release kernels, not -rc releases (it's nice to see the scope of Adrian's previous work increased).
