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?
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.
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.
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.
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.
Sorry for the confusion.
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
