This is what I find in the log:
Running transaction
RPMDB already locked by 22298
  The application with PID 22298 is: dnf
    Memory : 124 M RSS (686 MB VSZ)
    Started: Tue Jun 30 09:57:29 2015 - 03:30 ago
    State  : Sleeping
2015/06/30 10:00:59 akmods: Could not install newly built RPMs. You can find them and the logfile
2015/06/30 10:00:59 akmods: 346.72-2.1-for-4.0.6-300.fc22.x86_64.failed.log in /var/cache/akmods/nvidia/

So the problem is not with compilation, it's with dnf locking itself
out.

Running '/usr/sbin/akmods --force' solved it.

Not sure whether to report this against dnf or Nvidia.
