Just a possibility, but copying src tree to directory other than the
directory where checked out from git repo and building there could
lose track with git hash.

Another possibility is that if you build src with any user other than
the one owning local (pulled) git repo could also lose track with git
hash. For example, if I `git log HEAD` with regular user and the local
repo is pulled by root, it fails. No special configuration is done.

% git log HEAD
fatal: detected dubious ownership in repository at '/usr/src'
To add an exception for this directory, call:

        git config --global --add safe.directory /usr/src
