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.
