Fedora 8 test on Mac Pro ?

["Gabriel L. Somlo" <somlo cmu edu>]

I'm trying to set up Fedora 8 test on a Mac Pro, and while the install
completed smoothly, it hangs when booting from the hard drive, in
rc.sysinit, at or immediately after running /sbin/start_udev.

I booted off the rescue disk and ran yum update successfully. Now, it
manages to get as far as 'Setting hostname', still in rc.sysinit,
before freezing up completely.

Is this a known problem ? Any ideas about how to proceed pinning down
the root cause ?

Thanks much,
Gabriel
