More precisely: - The last working commit is b6dff3ec... "CRED: Separate task security context from task_struct". - The first commit exhibiting the permissions problem is a6f76f2... "CRED: Make execve() take advantage of copy-on-write credentials". - The 9 commits in between (from f1752eec to d84f4f9) result in a soft lookup on boot.
