Description v0k3 2014-04-11 15:57:53 UTC

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.

Please attach dmesg showing the problem.

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.

Oh sorry, I will do it right now.
Anyway how do I set the drm.debug parameter?
Do I have to start with 'drm.debug=0xe' by the bootloader?
Sorry again, v0k3.

That's correct. Usually you can do that at boot time, without making persistent changes, e.g. by pressing 'e' in grub/syslinux.

I've done it

Comment 9 Jani Nikula 2014-08-14 08:32:15 UTC

Sorry it seems we've ignored this bug a bit. Does the problem persist with recent kernels, say 3.16?

Comment 10 Jani Nikula 2014-09-12 10:09:45 UTC

Oops, we've totally failed to notice the HDMI is connected to the discrete GPU. Reassigning.

But audio now works for the user again:

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.

Right. 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.
