So I decided to use git bisect. However, sometimes I end up with a version before 2.6.26: $ cat .git/BISECT_LOG git-bisect start # good: [bce7f793daec3e65ec5c5705d2457b81fe7b5725] Linux 2.6.26 git-bisect good bce7f793daec3e65ec5c5705d2457b81fe7b5725 # bad: [3fa8749e584b55f1180411ab1b51117190bac1e5] Linux 2.6.27 git-bisect bad 3fa8749e584b55f1180411ab1b51117190bac1e5 # bad: [dd9ca5d9be7eba99d685d733e23d5be7110e9556] USB: usb-serial: fix a sparse warning about different signedness git-bisect bad dd9ca5d9be7eba99d685d733e23d5be7110e9556 # good: [84c3d4aaec3338201b449034beac41635866bddf] Merge commit 'origin/master' git-bisect good 84c3d4aaec3338201b449034beac41635866bddf $ head -4 Makefile VERSION = 2 PATCHLEVEL = 6 SUBLEVEL = 26 EXTRAVERSION = -rc8 If at this point I do a 'git bisect good' I end up in a 2.6.26 branch, which is good, but after a few bisects I end up at a version before v2.6.26 (2.6.26-rc5) again, which should be impossible right ? Anyway - at the end I end up with a 'good' version that is 2.6.26-rc which is kind of useless. I know that version up to 2.6.26 are good ... What am I doing wrong ?
