Fedora 21 won't boot after a routine update

I have a dual boot Fedora 21 / Windows 7 system. I've been using the Fedora 21 partition with no real problems for almost two months now. This partition runs off a mirrored pair of disks. The RAID is created using AMD's 2009 "RAID Option ROM Version 3.0.1540.59".

I do incremental updates of this system regularly. After this morning's update, the machine will no longer boot to the login screen: it hangs after the Fedora symbol is filled out and flashes. I don't remember the precise list of items, but it was about a dozen long.

When I enter rescue mode, I get

Generating "/run/initramfs/rdsosreport.txt"

Entering emergency mode.  Exit the shell to continue.
Type "journalctl" to view system logs.
You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot
after mounting them and attach it to a bug report.

Issuing the suggested command gives nothing

:/# journalctl
No journal files were found.

The rdsosreport.txt file follows:
