Noticed "Unknown error Occured" screen during installation of F19 alpha on P7 LPAR,by clicking on Debug button did not have any effect but it gets hungs. According the screen message , debug button should take you to the tty1 console and ctrl+alt+f16 should get you return. But it does nothing. Attached screenshot for reference "Screenshot-debug.png" to the bugzilla.
Please retry with Beta-TC4
