See the resolution here.
I recently got a PowerBook G4 (PowerBook5,6, 2005 model, 1.5GHz) that I want to get running on Mac OS X 10.5.8 so I can use Webkit, but I have a really odd problem I haven't been able to resolve.
It won't boot my retail Mac OS X 10.5 disc. Initially, it wouldn't read it at all, just spitting the disc out. I thought the drive could be the issue, so I attached an external optical drive. It did the exact same thing. The disc reads fine in my other computers and is what I've used on my Power Mac G4 and G5 in the past, so I know the disc works.
I tried imaging the disc over on my Mac Mini, and burning it onto one of my own dual-layer DVDs, and the laptop actually will read the disc, but only while it's running Mac OS X. It still won't boot to it. It has Mac OS X 10.4.11 right now, and I had no trouble installing 10.4 when I got it with its original restore DVDs. All other discs read fine in the laptop, except for my Mac OS X 10.5 disc. Remember that it behaves exactly the same way when using external disc drives.

Things I've tried:
- PMU reset
- PRAM reset
- NVRAM reset
- Reset-all in Open Firmware
- Force booting using Cmd+Option+Shift+Delete
- Force booting using C
- Force booting using Option
- Force booting from within Open Firmware (I tried a number of commands and parameters)
- Creating a bootable USB
- Repeatedly rebooting with disc in drive
