I've just compared the git messages from your link and from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc3-utopic/CHANGES and it
seems like the commits made to drm/radeon, are the only commits these two
kernel versions have in common.
Only seven of them are part of 3.15-rc3, which crashed on me yesterday, so it
would seem like the crashes are caused by one of those commits
