kernel 3.7 failed to boot -- Failed to start Wait for Plymouth Boot Screen to Quit

Hello,

I am trying kernel 3.7 vanilla into fedora 17 i686

When boot, the system shows

Failed to start Wait for Plymouth Boot Screen to Quit

My f17 is current using nouvea drivers, and when i am looking into the dmesg i got a

enable_msi not found

if i remove all xorg config file to nouvea, still not working ...

any clues?
