Mainline builds

The mainline builds of 2.6.34-rc2 and -rc3 have failed. Does anybody
know how to fix this?

Also, since around March 15 the mainline builds have a release name
associated to it (lucid and karmic). Could somebody explain the
significance of this or document it at ?

And while mentioning the wiki page, it would be nice if it could
explain in more detail what "Ubuntu kernel configuration files" means.
My experience is that copying e.g.
/boot/config-2.6.34-020634rc1-generic does not reproduce a mainline
build if I build it myself (e.g. I will have to turn kernel debugging
off in order to produce kernel-image*.deb < 30 MB instead of > 200
MB). The wiki page
suggests one needs to use the --overlay-dir option to make-kpkg with a
current ubuntu-git tree.

Finally, I'm currently not able to build 2.6.34-rcX using the
instructions at, but
I suppose that is related to the failing mainline builds, so leave
that out for now.

I understand you guys are busy preparing for the Lucid release, but
the missing mainline builds and difficult compile instructions make
triaging and upstreaming Ubuntu bugs and testing patches from upstream
much harder. For example, drm/i915 developers need more testing of the
patch at (LP:
541511) and I would have liked to prepare an Ubuntu package with that
so that some of the Ubuntu users who have reported this problem could
provide their test results without figuring out how to patch and build
a kernel.
