It seems to work for me. After creating a .config, I did: $ git bisect good v2.6.23 $ git bisect bad HEAD $ git bisect run make -j64 kernel/ Then I had to answer some configuration questions (I hit <enter> everytime) but it run fine. My git version is: git version 1.5.3.7.2200.g9275-dirty I attached the log (from git bisect log) and here is the end of the bisection: Bisecting: 74 revisions left to test after this [09f3eca2b7e2762e223fdd359f9d0f6303a85f6c] Merge branch 'for-2.6.24' of git://git.kernel.org/pub/scm/linux/kernel/git/galak/powerpc running make -j64 kernel/ scripts/kconfig/conf -s arch/x86/Kconfig # # configuration written to .config # CHK include/linux/version.h CHK include/linux/utsrelease.h CC arch/x86/kernel/asm-offsets.s GEN include/asm-x86/asm-offsets.h CALL scripts/checksyscalls.sh CC kernel/sched.o CC kernel/fork.o CC kernel/panic.o CC kernel/printk.o CC kernel/profile.o CC kernel/exec_domain.o CC kernel/exit.o CC kernel/itimer.o CC kernel/time.o CC kernel/softirq.o CC kernel/resource.o CC kernel/sysctl.o CC kernel/capability.o CC kernel/ptrace.o CC kernel/timer.o CC kernel/user.o CC kernel/signal.o CC kernel/sys.o CC kernel/kmod.o CC kernel/user_namespace.o CC kernel/pid.o CC kernel/rcupdate.o CC kernel/workqueue.o CC kernel/params.o CC kernel/posix-timers.o CC kernel/kthread.o CC kernel/kfifo.o CC kernel/posix-cpu-timers.o CC kernel/mutex.o CC kernel/hrtimer.o CC kernel/rwsem.o CC kernel/latency.o CC kernel/nsproxy.o CC kernel/extable.o CC kernel/wait.o CC kernel/utsname.o CC kernel/notifier.o CC kernel/sysctl_check.o CC kernel/futex.o CC kernel/srcu.o CC kernel/irq/handle.o CC kernel/power/main.o CC kernel/power/pm.o CC kernel/time/timekeeping.o CC kernel/power/process.o CC kernel/irq/manage.o CC kernel/time/ntp.o CC kernel/irq/spurious.o CC kernel/time/jiffies.o CC kernel/time/clockevents.o CC kernel/time/timer_list.o CC kernel/time/tick-common.o CC kernel/rtmutex.o CC kernel/dma.o CC kernel/cpu.o CC kernel/power/console.o CC kernel/irq/resend.o CC kernel/power/poweroff.o CC kernel/irq/chip.o CC kernel/irq/devres.o CC kernel/time/clocksource.o CC kernel/time/tick-broadcast.o CC kernel/irq/proc.o CC kernel/irq/autoprobe.o CC kernel/irq/migration.o CC kernel/uid16.o CC kernel/spinlock.o CC kernel/module.o CC kernel/acct.o CC kernel/kexec.o CC kernel/stop_machine.o CC kernel/kallsyms.o CC kernel/audit.o CC kernel/auditfilter.o CC kernel/ksysfs.o kernel/power/pm.c:205: warning: 'pm_register' is deprecated (declared at kernel/power/pm.c:64) kernel/power/pm.c:205: warning: 'pm_register' is deprecated (declared at kernel/power/pm.c:64) kernel/power/pm.c:206: warning: 'pm_send_all' is deprecated (declared at kernel/power/pm.c:180) kernel/power/pm.c:206: warning: 'pm_send_all' is deprecated (declared at kernel/power/pm.c:180) CC kernel/utsname_sysctl.o LD kernel/power/built-in.o LD kernel/irq/built-in.o LD kernel/time/built-in.o LD kernel/built-in.o Bisecting: 38 revisions left to test after this [e17587b5b90da78f56c7a948e54dbac3dc791f31] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hskinnemoen/avr32-2.6 running make -j64 kernel/ CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh Bisecting: 17 revisions left to test after this [c32bc6e9b0778c891f7f3b97cd05c8cdf98b6721] e1000: fix memcpy in e1000_get_strings running make -j64 kernel/ scripts/kconfig/conf -s arch/x86/Kconfig CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh CC kernel/sched.o CC kernel/hrtimer.o CC kernel/time/clockevents.o LD kernel/time/built-in.o LD kernel/built-in.o Bisecting: 8 revisions left to test after this [4696c3c406a8b32112f8e1f70b3db1114950dcb1] ibm_newemac: Correct opb_bus_freq value running make -j64 kernel/ CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh Bisecting: 4 revisions left to test after this [7962024e9d16e9349d76b553326f3fa7be64305e] S2io: Check for register initialization completion before accesing device registers running make -j64 kernel/ CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh Bisecting: 2 revisions left to test after this [d1aa690a7d1afa673c3383bfcd6e96ddb350939a] ata_piix: add Toshiba Tecra M4 to broken suspend list running make -j64 kernel/ scripts/kconfig/conf -s arch/x86/Kconfig CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh Bisecting: 1 revisions left to test after this [459ad68893a84fb0881e57919340b97edbbc3dc7] libata: kill spurious NCQ completion detection running make -j64 kernel/ CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh 94545baded0bfbabdc30a3a4cb48b3db479dd6ef is first bad commit bisect run success It found the HEAD as the first bad commit as expected, because I had no compilation error.
