Cool - that is helpful. I've updated the kernel on peri/penalosa with
the various patches listed there that have gone upstream, but I'm not
seeing better results with any failing packages.
btw, I thought it would be useful to edit that page and tag each patch
with its status in Debian (in-official-kernel, installed-on-buildds,
etc), but the page appears to be immutable.
