Hello, Ingo, I took the precaution of rebuilding my linux-2.6-tip from scratch as follows: 544 mkdir linux-2.6-tip 545 cd linux-2.6-tip 546 git-init-db 547 git-remote add linus git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git 548 git-remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git 549 git-remote update 550 git-checkout tip-core-rcu-2008-06-16_09.23_Mon The "git-checkout" command complained as follows: warning: You appear to be on a branch yet to be born. warning: Forcing checkout of tip-core-rcu-2008-06-16_09.23_Mon. Checking 24254 files out... 100% (24254/24254) done fatal: ambiguous argument 'HEAD': unknown revision or path not in the working tree. Use '--' to separate paths from revisions Cannot detach HEAD In addition, the kernel/rcutorture.c file does not have the "stutter" changes in it after doing this checkout. Did I mess something up? Am I working with a too-old version of git (git version 1.5.2.5)? Or has git simply taken a deep and personal disliking to me? ;-) My next step will be to try a more recent version of git. In parallel, I will just re-do the patch on top of my patch stack. Thanx, Paul PS. I am assuming that the repeated messages from git-update of the following form are expected behavior when there are tags: * refs/tags/tip-x86-xsave-2008-05-26_08_54_Mon: storing tag 'tip-x86-xsave-2008-05-26_08_54_Mon' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip commit: d40ace0 -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
