F22: rebooting to emergency mode
I have done a fresh install of Fedora 22 on the same computer 4 times.
Each time, after using the system from 1 day to 3 days and having
successfully rebooted several times, a reboot results in being started
in emergency mode. This computer was running Fedora 21 since its release
without any problems. I am using an ASUS P9X79 Deluxe motherboard.
At the emergency mode console the following is displayed in yellow:

I have tried installing to a new hard disk. I have tried a different
video card. I have run fsck on the hard disk after booting a live image.
No errors were found. Nothing I have tried has changed the result.
Where do I start in order to determine the cause of this problem?
