Comment 1 Kamil Páral 2010-08-06 08:58:47 UTC 
Confirmed on F14 Alpha RC1 DVD x86_64 image.
Comment 2 Chris Lumens 2010-08-06 12:29:46 UTC 
Please attach the complete kernel log.  We have not changed anything in the image building process that I am aware of, so this is unlikely to be an anaconda problem.

Diff comparing initrd.img content from TC#2 and RC#1

I looks like there is significant "stuff" missing from the initrd.img for RC#1.  Attaching a diff comparing the contents of the initrd.img between RC#1 and TC#2.

dgilmore is trying to identify the root cause of this issue, which seems to be related to the compose process.
Comment 6 Paul W. Frields 2010-08-06 17:07:49 UTC 
By the way, the compose is being tracked by the rel-eng team here:
