Created attachment 359179 [details] output of lspci -nn Description of problem: When I boot the kernel from the F12 Alpha DVD, the computer freezes. When the kernel boots, I see a lot of text go by starting with "Loading vmlinuz". The second of last line of the text "detecting hardware..." I believe that the last line is "waiting for hardware to initialize..." After that, I believe that the video mode is being set because the font size becomes smaller. There is a steady cursor which is on the left side of the screen about 40% from the top. When the computer freezes, it can be rebooted with C-A-D. I see exactly the same results whether I select any of the following options on the initial menu: = Install or upgrade an existing system = Install system with basic video driver = Rescue installed system Version-Release number of selected component (if applicable): The kernel from the Fedora 12 Alpha DVD (i386 architecture). How reproducible: Happens every time. Steps to Reproduce: 1. Boot F12 Alpha i386 DVD 2. Select option in initial menu to boot the kernel. Actual results: After some initial text is displayed, the computer freezes with a steady cursor. Expected results: The boot should not freeze and allow the user to install the OS. Additional info:
I was able to install by adding the kernel parameter radeon.modeset=0.
When the kernel was updated to 2.6.31-0.190.rc8.fc12.i686.PAE, the computer became able to boot without the radeon.modeset=0 parameter. However, the monitor now goes into powersave mode when the graphical boot is running.
