Bisecting produced d050f8ed14494ea23c6e10b5893010946ef0f78b as the first bad commit, although on this commit the machine hangs immediatly after boot, so it might be a different issue.
Since you can't test that commit for this problem, you should run
git bisect skip
for it, not "bad". Does the following commit boot and exhibit the problem?
