REGRESSION 3.14 i915 warning & mouse cursor vanishing

From: Steven Noonan
Date: Mon Apr 14 2014 - 12:40:40 EST

Was using my machine normally, then my mouse cursor vanished. After switching
to a VT and back to X11, my cursor came back. But I did notice a nasty trace in
dmesg (below).

I have a few options specified on my command line related to i915, but these
worked fine through 3.13.9:

i915.lvds_downclock=1 i915.i915_enable_rc6=7 i915.i915_enable_fbc=1

System is a Lenovo ThinkPad S1 Yoga.

Let me know what other information would be helpful. I could do a bisection if
needed, but I'm hoping the stack traces below trigger an "aha" moment in somebody.

Here's the trace:
