You appear to be booting with 'nomodeset' on the kernel command line.  This is, broadly speaking, unsupported.  Why are you doing that?
Comment 4 Adam Jackson 2012-02-13 17:48:22 UTC 
Closing per comment #2.  'nomodeset' is a diagnostic tool only, not a supported configuration.  If you can reproduce this issue without 'nomodeset' on the kernel command line, please reopen.
