I am trying to install fedora on a pSeries 615 - 7029-6C3. This is with fedora 11 ppc. When I start linux32 it says
loading ramdisk
....
Building dt srings
Building dt structure
Device tree string 0x....
Device tree structure 0x....
Calling quiesce
Returning from prom_init

Edit: I tried it today with fedora 12 ppc and I get the same problem.
