What do I want to skip or avoid testing though? Does bisect not know how to deal with merges? Here is the log, in case that helps: 4cc4d24efce4672f9b0e7fa27963770ae602998f is the first bad commit [greearb@build-32 linux-2.6]$ git bisect log git bisect start # bad: [85f2e689a5c8fb6ed8fdbee00109e7f6e5fefcb6] Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86 git bisect bad 85f2e689a5c8fb6ed8fdbee00109e7f6e5fefcb6 # good: [521cb40b0c44418a4fd36dc633f575813d59a43d] Linux 2.6.38 git bisect good 521cb40b0c44418a4fd36dc633f575813d59a43d # skip: [ec0afc9311adcfb10b90e547c23250f63939f990] Merge branch 'kvm-updates/2.6.39' of git://git.kernel.org/pub/scm/virt/kvm/kvm git bisect skip ec0afc9311adcfb10b90e547c23250f63939f990 # good: [a99eff39c0549fe68fed150d39ec0c750e5ce1f1] powerpc: Document the Open PIC device tree binding git bisect good a99eff39c0549fe68fed150d39ec0c750e5ce1f1 # bad: [17e75d82518ac3146966b64adc109344fcc80f8a] ARM: mach-shmobile: convert boards to use linux/mmc/sh_mobile_sdhi.h git bisect bad 17e75d82518ac3146966b64adc109344fcc80f8a # bad: [4cc4d24efce4672f9b0e7fa27963770ae602998f] Merge git://git.kernel.org/pub/scm/linux/kernel/git/lethal/fbdev-2.6 git bisect bad 4cc4d24efce4672f9b0e7fa27963770ae602998f # good: [943fc810bdc9c0fce5cc66bdb65b42d699241aa6] MAINTAINERS: update SFI pattern git bisect good 943fc810bdc9c0fce5cc66bdb65b42d699241aa6 # good: [3486740a4f32a6a466f5ac931654d154790ba648] userns: security: make capabilities relative to the user namespace git bisect good 3486740a4f32a6a466f5ac931654d154790ba648 # good: [38d2620ea40c2f9a5f17d6488bf004973570279c] svga: Make svga_set_timings() take an iomem regbase pointer. git bisect good 38d2620ea40c2f9a5f17d6488bf004973570279c # good: [2f284c846331fa44be1300a3c2c3e85800268a00] Merge branch 'devel' of master.kernel.org:/home/rmk/linux-2.6-arm git bisect good 2f284c846331fa44be1300a3c2c3e85800268a00 # good: [d6244bc0ed0c52a795e6f4dcab3886daf3e74fac] fbcon: Bugfix soft cursor detection in Tile Blitting git bisect good d6244bc0ed0c52a795e6f4dcab3886daf3e74fac # good: [26947f8c8f9598209001cdcd31bb2162a2e54691] proc: disable mem_write after exec git bisect good 26947f8c8f9598209001cdcd31bb2162a2e54691 # good: [d958c62c0cf43bb9c7dcd9833a35335ae72856f7] MAINTAINERS: Add file pattern for fb dt bindings. git bisect good d958c62c0cf43bb9c7dcd9833a35335ae72856f7 # good: [198214a7ee50375fa71a65e518341980cfd4b2f0] proc: enable writing to /proc/pid/mem git bisect good 198214a7ee50375fa71a65e518341980cfd4b2f0 # good: [b81a618dcd3ea99de292dbe624f41ca68f464376] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6 git bisect good b81a618dcd3ea99de292dbe624f41ca68f464376 # good: [56be1416453c31d32f984328b5193489ab63ffcf] MAINTAINERS: de-orphan fbdev. git bisect good 56be1416453c31d32f Thanks, Ben > > Jeff > -- Ben Greear Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
