Linux/kernel has a tag object which doesn't have commit. GitHub doesnot show this reference

object c39ae07f393806ccf406ef966e9a15afc43cc36a
type tree
tag v2.6.11-tree

This is the 2.6.11 tree object.

NOTE! There's no commit for this, since it happened before I started with git.
Eventually we'll import some sort of history, and that should tie this tree
object up to a real commit. In the meantime, this acts as an anchor point for
doing diffs etc under git.
