Hello, I have recently installed FC3 in a Toshiba Tecra laptop, and I had the same problem as you.
FC3 always hanged up when trying to initialize the hardware. I rebooted my laptop using the rescue cd so I could get a prompt shell to execute a
command and see what was happening. In the huge list of messages I saw one telling me to boot the kernel with the acpi option switched to OFF. I did it and it worked for me.
You can pass that parameter to the kernel for the current boot in this way:
When Grub starts and shows you the list of available OS for booting on your machine, highlight the 'Fedora Core (2.6.9-1.667)' line or whatever you have and press the 'e' key to edit it. Next highlight the one titled as
kernel /boot/vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet
and press 'e' again. Now add the
param at the end and press enter. You will see the new kernel booting line properly modified. Next, press the 'b' key to boot with it (don't forget to highlight it if you haven't) and your system should boot now perfectly. I hope so
As I have told you this fix the booting problem just for this time, so to do permanent the changes you have to edit your
file and add there the acpi=off param.
