But I seeked help to choose=20 exactly which commit. Well I now go with martin@shambhala:~/Computer/Shambhala/Kernel/2.6.33-2.6.34- bisect/linux-2.6> git log | head =20 commit a27341cd5fcb7cf2d2d4726e9f324009f7162c00 Author: Linus Torvalds Date: Tue Mar 2 08:36:46 2010 -0800 Prioritize synchronous signals over 'normal' signals =20 This makes sure that we pick the synchronous signals caused by a processor fault over any pending regular asynchronous signals sent to use by [t]kill(). When I interpret the graphical display of gitk correctly this one should=20 be directly before the whole lot of KMS/DRM/Radeon/Intel commits being=20 merged. Now hopefully this one boots. And is good. Then I would have skipped a=20 whole lot of the revisions to test. But even when it just boots, but is=20 bad, I at least know that its not in these merges.
