Sorry about the delay. The patches don't seem to fix the issue for me. Please see the Xorg log attached. I tested the patches as follows. Given that my bisection had been done in a Fedora 24 guest, using xorg-x11-server-1.18.4-4.fc24 http://koji.fedoraproject.org/koji/buildinfo?buildID=794494 I now rebuilt the guest kernel exactly at the failing commit (a325725 "drm: Lobotomize set_busid nonsense for !pci drivers"), and first reproduced the issue with the above X server. Then, I ported your patches to "xorg-server-1.18.4" (using the upstream xserver tree), and rebuilt the Fedora package with the backport. For the backport, I had to cherry-pick the following two patches from master first: 1 ca8d88e50310 xfree86: recognize primary BUS_PCI device in xf86IsPrimaryPlatform() 2 ea91db4b8331 config: fix GPUDevice fail when AutoAddGPU off + BusID This way your patches applied cleanly. (Cherry pick #1 above is actually necessary for semantics, while cherry pick #2 is needed for a clean context only, and has no impact for this test.) That is, in total, I added the following four patches to the Fedora 24 package: 1 xfree86: recognize primary BUS_PCI device in xf86IsPrimaryPlatform() 2 config: fix GPUDevice fail when AutoAddGPU off + BusID 3 xfree86: Make adding unclaimed devices as GPU devices a separate step 4 xfree86: Try harder to find atleast 1 non GPU Screen You can find the scratch build that I used for testing here: xorg-x11-server-1.18.4-4.hans_bz1366842_2.fc24 http://koji.fedoraproject.org/koji/taskinfo?taskID=15875087 Another reason I used F24's X server as basis, rather than upstream HEAD, is that Fedora 24 is pretty young, and it's already on kernel 4.7.4, and I believe it will soon move to kernel 4.8, without (necessarily) rebasing its X server package to upstream. IOW the kernel upgrade to 4.8 will break X in Fedora 24 too, and then I expect the Fedora X maintainers would have to cherry pick those two patches as dependencies just the same. To summarize, the patches don't seem to help. I shall nonetheless thank you for spending your Friday on this! Laszlo -------------- next part -------------- A non-text attachment was scrubbed...
