I can't boot ether Gentoo 2004.* LiveCD's under a OldWorld PowerMac 7200. Aparently the 601 chip inside can't handle the G4 kernel, as I get nothing after the penguin display. Reproducible: Always Steps to Reproduce: 1. Boot normally into MacOS (I'm using 9.1) 2. Start BootX, using the G4 kernel, initrd.img.gz as the ramdisk, size 32768, command line "init=/linuxrc". (Another try with the same paramaters as in yaboot.conf resulted in the same problem) 3. Start it off... and wait... Actual Results: Penguin shows, nothing else. After five+ minutes, reboots. Expected Results: Should be inside installing Linux!!! The 1.4 LiveCD didn't have this problem. However, it had the SCSI disk driver prob that frose that. Maybe a truly generic PPC kernel needs to be compiled.
Can you try passing the following extra arguments: video=ofonly The G4 kernel is something that should boot everything powerpc but nubus and G5.
Ah, and don't forget passing 'root=/dev/ram0' and 'cdroot' as arguments.
Nope, but the CD is being accessed though. I wonder if the platnum FB is supported...
Negative on all. Even video=platinumfb: fails. I'll have to do a Slackintosh 8.1 boot to do the setup.
Probably video=platinumfb is not in the kernel. Is there a 2.6 kernel option to enable this?
Yes. FB_PLATINUM. You may need to also install FB_CONTROL and FB_VALKYRIE, some older Powermacs use them too. FB_MAC should also be in.
Same problem happens on a G3 beige tower, OS 8.6 ramdisk set as specified (size 32768) Passed to kernel: init=/linuxrc root=/dev/ram0 video=ofonly cdroot Mac OS shuts down and the following appears on the screen: Welcome to Linux Kernel 2.6.5-gentoo-G4 linked at :0xc0000000 frame buffer at :ox81801400 (phys), 0xd0801400 (log) klimit :0xc0d30000 MSR :0x00000072 HID0 :0x210e0ac ICTC :0x00000000 pmac_init():exit id mach():done MMU:enter MMU:hw init hash:enter hash:fine piece hash:patch hash:done MMU:mapin MMU:setio MMU:exit setup_arch:enter setup_arch:bootmem arch:exit This is similar to what shows up when YDL 3.0 boots, right before the kernel starts loading. Except with the Gentoo kernel it never goes any farther. Thanks for any help you can give.
Could you try the 2004.2 livecds. This should be fixed, if not please reopen this bug.
This was tested using the 2004.2 CD initally.
I've verified the needed options are enabled in the kernel. We're also working on an oldworld special edition cd that might come with a 2.4 kernel as default.
kernel = 2004.3 kernel btw
OK, I've been away from this problem for a long time, but just tonight got around to trying your suggestion of booting from a 2004.2 LiveCD. I had a hell of a time figuring out where to get it. Anyway, the kernel on the 2004.2 LiveCD boots just fine using the kernel parameters in the yaboot.conf that comes with that CD: "root=/dev/ram0 init=/linuxrc looptype=squashfs cdroot" It is possible that I mangled the 2004.1 kernel while using Fetch (a Mac program) to FTP it from my other linux box. Apparently you can't leave the file type at "auto" -- you MUST check "binary" for both the kernel and the initrd. I haven't gone back to retry it because the 2004.2 kernel is working and the filenames are the same.
I can boot the 7200 using the 2004.3 kernel, and the new line. I've filed bug 71627 over the bug in the documentation. Should be in there properly. I think I can close this bug now...
Closing bug due to testing verified.
I still have this problem with all 2004.X kernels. I just see the penguin logo and no boot messages. (Booting with: rw root=/dev/ram0 init=/linuxrc looptype=squashfs cdroot didn't helped) This is an OldWorld Power Macintosh 8500/150 with 0001:01:0b.0 Non-VGA unclassified device: Apple Computer Inc. Control Video controller. I had installed gentoo to this computer using gentoo's livecd 1.2. And now can compile a kernel (2.6.9-gentoo-r6) that boots (with Kernel command line: root=/dev/sdc7 video=ofonly), but i still get the penguin logo, and after some time a black display, but i can login over ssh.

Updating status.
