Hi,

  I would like to create a branch of my own work based on a specific
kernel version(i.e
v2.6.11). I tried with:

git-branch my2.6.11 v2.6.11

error: Object 5dc01c595e6c6ec9ccda4f6f69c131c0dd945f8c is a tree, not a
commit
fatal: Needed a single revision
   

What you're after is

  git-rev-parse --verify <tagname>^0  > .refs/heads/mynewbranch

"branches" are very lightweight -- it's a ref containing the SHA1 of
the commit you want it to be at. So if you find the SHA1 of the commit
in gitk or wherever, just

 echo SHA1 > .refs/heads/mynewbranch

and you're sorted. Do git-checkout to switch to it.

cheers,

The command complains:

   >git-rev-parse --verify v2.6.11^
   error: Object 5dc01c595e6c6ec9ccda4f6f69c131c0dd945f8c is a tree, not

I think it need another way to convert a tag/tree object into a commit ?
