             (Ok, it's queued up for after 2.6.22 is out as it is not a regression and is kind of intrusive.)

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).
