I upgraded to 4.0.4 from a 4.0.0 build I was running. Initially everything seemed fine.

The corruption occurred several hours later after I started an update run and during 
the run ldconfig was spitting out "bad ELF" errors. I corrected those that were 
reported, but upon a reboot it had corrupted even more files and the system was no 
longer bootable due to corruption to libXfont and a few other libraries.

I was able to salvage the system after downgrading to 4.0.1 and re-installing rpm, 
yum, and a couple dozen other packages.

The problem may only be related to >4.0.2 and mdadm RAID. I won't have time right 
this minute, but if no one else can easily reproduce it I will setup a VM with two 
drives and see if that's enough.
