Macbook Air 2012

Macbook Air 2012

[Daniel Wagner]

Hi,

I installed on my shiny new Macbook Air 2012 Fedora 17. After adding

intremap=off

to the kernel arguments, I was able to install the system. The X server 
worked out of the box. This was with a 3.3.4 kernel.

Then I started to upgrade the installation and a newer kernel was 
installed 3.5. After the reboot the screen stayed black. Upgrading to 
Linus' 3.6-rc1 didn't help either.

After some research I have tried now Daniel's tree danvet branch 
drm-intel-next. Still no success. I also found 
https://bugs.freedesktop.org/show_bug.cgi?id=48652 which sounds awfully 
like what I am seeing as symptoms.

Unfortunately, is my graphic trouble debugging skills rather limited. Is 
there anything I could provide to resolve this issue?

cheers,
daniel

ps: Adding nomodeset to the drm-intel-next kernel resulted in a kernel 
panic:

http://www.monom.org/misc/mba/drm-intel-next_nomodeset-2012-08-11.jpg

Don't know if that is important. Just in case someone is interested in 
these kind of reports.

I think there is a fix already [1].

Nope, that's the fix for the new retina macbook pro. Daniel, if you can,
please test the latest patch attached to that bug report and reply on the
bug report with the result.

Thanks, Daniel

Done as you have requested. Unfortunately, the screen is still black. 
But there seems to be a small improvement. I see for a short time some 
kernel boot message before it turns off.

cheers,

I've pointed you at the wrong bug report unfortunately. This one is the
right one:

https://bugzilla.kernel.org/show_bug.cgi?id=45671

Please test the "patch v3" on that bug.

Sorry for the confusion.
-Daniel

Applied v3 and I see for a short time kernel messages, then the screen 
goes black, then I think 2 times the backlight goes on and off and then 
it stays black without backlight.

No problem. I happy to test patches. I'll have to create an account on 
bugzilla.kernel.org to add the test results.

cheers,
daniel

Got it working. I bet that I did something stupidly wrong. With this 
patch on top of Linus' tree with the Fedora kernel configuration all is 
fine.

Now I am rebuilding the drm-intel-next tree with the patch and the 
Fedora configuration. Let's see if I did something stupid :)

daniel
