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
