You can always try to add the acpi=off as kernel parameter.
(Any key to interupt automatic boot then Tab to edit option append 
acpi=off to the end then press enter to boot)
I would suggest you to read the
http://fedoraproject.org/wiki/Common_kernel_problems
especially the Crashes/Hangs section.
I hope it helps.
