I have been seeing the same thing you're seeing.  I haven't tracked down the cause as of yet.
 
However, after doing the dnf upgrade of the kernel check in /var/cache/akmod and check the log.  You may see something like this....

[root at meimei akmods]# tail akmods.log
2015/06/28 18:25:41 akmods: Building and installing nvidia-304xx-kmod
2015/06/28 18:25:41 akmods: Building RPM using the command '/bin/akmodsbuild --target x86_64 --kernels 4.0.6-300.fc22.x86_64 /usr/src/akmods/nvidia-304xx-kmod.latest'
2015/06/28 18:26:00 akmods: Installing newly built rpms
2015/06/28 18:26:01 akmods: Could not install newly built RPMs. You can find them and the logfile
2015/06/28 18:26:01 akmods: 304.125-3.10-for-4.0.6-300.fc22.x86_64.failed.log in /var/cache/akmods/nvidia-304xx/
2015/06/28 18:26:01 akmods: Hint: Some kmods were ignored or failed to build or install.
2015/06/28 18:26:01 akmods: You can try to rebuild and install them by by calling
2015/06/28 18:26:01 akmods: '/usr/sbin/akmods --force' as root.

At this point you have 2 choices.  Check the /var/cache/akmods/nvidia-"driver" directory to see if the rpm has actually been built or run the command as a user as shown in the log.  In the case above it would be

/bin/akmodsbuild --target x86_64 --kernels 4.0.6-300.fc22.x86_64 /usr/src/akmods/nvidia-304xx-kmod.latest

and install the resulting rpm.
