After the last update to the kernel version 3.14.0.4 I get this error on boot: "drm:I915_stolen_to_physical" and my HDMI's sound doesn't work anymore.. I just downgraded the kernel to 3.13.8-1 and it works (no errors). I'm on Arch Linux x86-x64 with an intel's CPU i7 (2600 or 2700) and as vga I have a Radeon HD 7770. Sorry for bad english.
audio now works (3.14.1-1) but i still get the error.
Please attach dmesg showing the problem.
here there is my last boot dmesg: http://pastebin.com/W9EPz5Ni
(In reply to v0k3 from comment #3) > here there is my last boot dmesg: http://pastebin.com/W9EPz5Ni Apologies, I forgot to ask for dmesg with drm.debug=0xe module parameter set. Also, please always attach ("Add an attachment" above) the logs instead of using pastebin. Thanks.

Do I have to start with 'drm.debug=0xe' by the bootloader? Sorry again, v0k3.

Created attachment 134211 [details] dmesg with debug

Sorry it seems we've ignored this bug a bit. Does the problem persist with recent kernels, say 3.16?
Oops, we've totally failed to notice the HDMI is connected to the discrete GPU. Reassigning.

What he still complains about is: "drm:I915_stolen_to_physical" If that isn't critical or already fixed I think we can close the bug now.

Sorry for the noise. Thanks for the report anyway. Please file a new bug against DRM/Intel at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI if the problem with drm:I915_stolen_to_physical persists with recent kernels.
