I also think it's not a kernel bug (I didn't relate the bug report to it) cause the kernel panic appears at boot begin, when no modules were loaded.
In the other report they talk about yaboot as guilty one. An initrd problem is also probable. -- Powerbook G4 kernel panic https://launchpad.net/bugs/55454 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
