Caused by commit a25ca17c1eac ("drm/i915: Do not dereference pointers from ring buffer in evict event").
I have used the drm-intel tree from next-20140318 for today.
Bah! I'm still suffering from jet lag (just came back from Linux-Tage in Chemnitz).
The next time I compile test a patch for a module, I'll make sure I have that module's config option set :-( The woe of using localmodconfig. I should have picked the box with the i915. :-/
Below is the fix. I'll repost a v2 of the original patch.
Sorry about that.
I was about to send out the same fix when I saw this.
