Description of problem:
"An error occurred unmounting the CD." stops installation from proceeding.

Version-Release number of selected component (if applicable):
FC6 Test3 v5.92

How reproducible:
Always happens

Steps to Reproduce:
1. Install FC 5.92 "new installation"
2. Choose "desktop" type
3. Choose [ok]
This is a Centrino laptop, and "linux mediacheck" from the same install CD
doesn't have any problems ejecting the CD.  I didn't have this problem with FC5.
  
Actual results:
An error occurred unmounting the CD. Please make sure you're not accessing
/mnt/source from the shell on tty2 and then click OK to retry. The only choice
is to choose [OK] and it just repeats the error.

Expected results:


Additional info:
I looked at tty2 ([ctrl-alt-F2]), and it didn't look like anything was happening
there.  I tried mounting and mounting from that tty, but didn't make any progress.
