Subject: Radeon crash with v3.13-rc3-157-g17b2112

Hi All,

Booting today's rawhide kernel fails on my Dell XPS 8300 machine.  I
added nomodeset to the command line because it seemed to glitch out
when doing the handoff to the radeon driver and that let me boot far
enough to start networking.  I then loaded the radeon driver with:
modprobe radeon modeset=1 and was greeted with the backtrace below.

I haven't done a bisect yet, but I can if needs be.  I was hoping this
would trigger someone's memory.  Plain 3.13-rc3 works, so it's
something in the DRM merge that Linus did after -rc3.  Given the
backtrace, this one might be suspect:
