But it seems that the two approaches gives a different results. (Cc'ing the git mailing list as they might know the reason) git-describe f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2 returns "v2.6.26-rc8-1107-gf4c1f3e" While you URL returns: "X-Git-Tag: v2.6.27-rc1~964^2~219" I also did a: "git log v2.6.26..v2.6.27 | grep f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2" commit f4c1f3e0c59be0e6566d9c00b1d8b204ffb861a2 To Radu: The change I talked about is in 2.6.27, so you should try that kernel on you system.
