But compiling -rc5 (as the bug is strill present in -rc5) fails with: /usr/local/src/linux-2.6-git/arch/powerpc/kernel/crash.c: In function ‘default_machine_crash_shutdown’: /usr/local/src/linux-2.6-git/arch/powerpc/kernel/crash.c:349: error: implicit declaration of function ‘crash_kexec_wait_realmode’ make[2]: *** [arch/powerpc/kernel/crash.o] Error 1 make[1]: *** [arch/powerpc/kernel] Error 2 make: *** [sub-make] Error 2 Maybe I'll just disable kexec and see if TREE_RCU helps. Meanwhile, I gave up on the git bisect, as I can hardly boot inbetween commits: http://nerdbynature.de/bits/2.6.39-rc4/oom/git-bisect-log.txt Thanks, Christian. -- BOFH excuse #446: Mailer-daemon is busy burning your message in hell. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
