Kernel log

I've got this bug anytime I've tried starting drm-next on my BONAIRE HD7790. It
boots fine, kms seems to work in the console. However, as soon as the X-server
is started the kernel reports a null pointer dereference and it's impossible to
start another X-server instance after.

Kernel version: v3.10 + git://people.freedesktop.org/~agd5f/linux drm-next-3.11
(Jul 6)
xf86-video-ati (git Jul 6)
mesa (git Jul 6)
libdrm (git Jul 6)
llvm (svn Jul 6)

With 
kernel: 3.11.3 gentoo version
mesa: git(Oct 3) builded with gles
xf86-video-ati: git(Oct 3)
libdrm: git(Oct 3)
llvm: git(Oct 3)
glamor: git(Oct 3) builded without gles

I can boot to kde (with radeon.dpm=1 in kernel cmdline) but some activity in
firefox leads to GPU lockup, what has nothing to do with this bug.
Without gles in mesa I can't boot at all. As described before.
Maybe it'll help find problem.

Bonaire works fine here. Feel free to reopen if you still have this issue, but
please update your driver components first.
