Bug#703468: [3.2.35-2 - 3.2.39-1 regression] fails to boot on apple iMac

Jonathan reported this to sta...@vger.kernel.org on the same day as above, and Greg KH said the 9a0f938bde74 change is now applied (presumably to the 3.4.y tree), and Luis Henriques replied saying he's queued it for 3.5 as well. I'd still like to know if/how/when this will be fixed for the Wheezy release though. This bug report is not Release Critical, so I doubt it will get in before Wheezy releases (I would like Debian Wheezy to be installable on apple imacs, but I'm not sure it's feasible at this stage of the release process). But will it be queued up for the first point release of Wheezy? Cheers, Geoff -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Hopefully it reproduces the bug. So I followed the above instructions, though I did a 'git checkout v3.4.4' instead of 'git checkout stable/linux-3.4.y'. This produced a linux-image-3.4.4_3.4.4-1_amd64.deb file that I installed. This kernel failed in the same manner, as we hoped. 4. try the patch: cd linux git cherry-pick -x -s 9a0f938bde74bf9e50bd75c8de9e38c1787398cd make deb-pkg; # maybe with -j4 dpkg -i ../name of package; # as root reboot ... test test test ... I ran the 'cherry-pick' command, and redid the make deb-pkg and dpkg -i steps. When I rebooted onto that kernel it worked fine. So it seems this patch fixes the 3.4.4 kernel. What git invocation should I do to test a debian Wheezy kernel? (on Monday morning, as I'm leaving the office now).

Thanks again and sorry for the trouble, Jonathan I can confirm the patches are not independant. I found bugfix/x86/drm-i915-Only-kick-out-vesafb-if-we-takeover-the-fbc.patch didn't apply if the above patches weren't included (because I'd commented them in the series file). But I didn't get any further along that line of development. Instead I downloaded linux_3.8.5-1~experimental.1.dsc (and related) and tried to build that on my wheezy box. The build failed after a long time, but well after it had successfully built linux-image-3.8-trunk-amd64_3.8.5-1~gc70.1_amd64.deb. So I tried to install that (and found I also had to download and compile the initramfs-tools 0.110 package). But now I'm running the 3.8.5 kernel successfully. So this bug is not present in a 3.8.5 kernel. I guess given Jonathans comments on 2013-04-02 I should keep trying to build a 3.2.39 package without some selection of the above patches (and whatever else) to see if that does work, and then try adding back in patches until it fails.
