I've been using that branch at commit 0279ed19bd962434d334f5eeb16d14fdd9459a00
and things seems a little better but it keeps crashing with my Radeon HD 6870.

Most of the time, the kernel boots, but sometimes it freezes right at the
start.
First thing I notice with that kernel it's that I see the Tuxs for a second
before Plymouth, maybe it's something related to the initrd, I don't know.
I'm able to log in and even sometimes load a 3D game and play, but it always
end crashing after a few seconds.

I've trying to do a kdump, but the system is totally unresponsive.

What can I do to help?
