For the oops message (well it's just a WARNING, a real oops would kill
your driver for real) please file a bug report on bugs.freedesktop.org
against dri -> drm (intel).

The information we need is the full dmesg fore the entire boot when
enabling drm.debug=0xe on the kernel cmdline.

For the boot hang you've reported on the redhat bz if you want to move it
forward I suggest to do a reverse bisect betwen 3.13 and 3.14-rc7 to
figure out which bug _fixed_ your problem and then tell me that. I'll
submit it for backporting to stable kernels. Google should find you some
nice howtos for reverse bisecting kerneels.

Cheers, Daniel
