You have to look at the output of that command to determine whether it
succeeded. If the affected files have changed since that commit was
made, the revert may not work.

If the revert fails, or reverting on top of a later revision does not
solve the problem, you should recheck your regression result by doing
the following:

$ git bisect reset
in case you're in the middle of a bisect.

$ git reset --hard 7cb044d3d8aaf1cee629c259f19177732bed37af
Rebuild and test. This should be a "bad" revision.

$ git reset --hard 7cb044d3d8aaf1cee629c259f19177732bed37af
Rebuild and test. This should be a "good" revision.

$ git reset --hard origin/master
to get back to the latest revision.
