--- Comment #47 from Alexandre Demers alexandre.f.demers@gmail.com 2012-06-08 10:37:24 PDT --- The latest patch is a no go on Cayman (running kernel 3.5-rc1, with latest mesa, drm and DDX). When booting, 3D is unavailable and I have to use the 2D gnome-shell version. Reverting the v6 patch, 3D is back again.
I'll attach some files at the end of the day (dmesg, .xsession-errors, Xorg log) about the errors.
