output of lspci -vv, output from gdb, xorg.conf

Whenever I start a graphical application like iceweasel, icedove, gajim etc. X crashes. I use i3 as a window manager and dmenu to start programs. If I replace the radeon driver by the vesa driver X doesn't crash.

I use debian testing and installed the following packages:

xserver-xorg-video-radeon
xserver-xorg-video-radeon-dbg
xserver-xorg-core
xserver-xorg-core-dbg

but the output from gdb is full of "file xy not found" messages.

Already fixed in Git. BTW, you wouldn't have hit this bug with KMS, any particular reason why you've disabled that?

I didn't disable KMS on purpose, I just didn't enable it because I didn't know about it.

Now I enabled KMS by changing the first line in /etc/modprobe.d/radeon-kms.conf from "options radeon modeset=0" to "options radeon modeset=1", running "update-initramfs -k `uname -r` -u" and rebooting and now it works :-)

Thank you for your help.
