Fedora 16: can't boot ppc-DVD

[Federico Vaga]

I'm trying to install Fedora 16 on a powerbook G4; on boot the system return 
continuously  the following error:

Machine check in kernel mode.
Caused by (from SRR1=149030 ) Transfer error ack signal

so I can't installa Fedora 16.

(No problem with ppc64-DVD on an iMac G5)
