When I first cloned the kernel repo, I did git tag -l, and I'd swear that there were only tags of the form v.(-rc[0-9]+)? but now I give the same command again I get tags like v..(-rc[0-9]+)? That's why I tried to build 3.10 and 3.11. I might be going mad. I know I'm tired, but this is a whole new level of insanity! I'll try building 3.10.11 from git and report back. Nick/.
