installing akmod-nividia on F20 - machine hang after reboot, "Started Builds ..."

[David Shwatrz]

Hello, fedora users,
I have an Nvidia graphic card. Instead of using the default nouveau
driver, I installed akmod-nvidia (simply by yum -y install
akmod-nvidia)

Now first time after installing akmod-nvidia and restarting the
machine boot hanged with this message:
[OK] Started Builds and install kmods from akmod packages.

I waited for more than 10 minutes and nothing happened, I cannot boot.
Any ideas ? what should I do so that it will boot OK ?

regards,
DavidS
