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:
