live cd g4 1.4 always a kernel panic on tibook

hi all, Needing help here for getting through with a linux install on my tibook 500mhz, the disk partition has already been done, a debian hard drive space of 8gig waiting for it. [havent got yet to put my hands on mac fdisk]

I have d/l'd a gentoo-ppc live cd [1.4 g4] but it gives a kernel panic all the times just after checking all the hardware components, freeing unused kernel memory and using cloop.o then:

insmod: init_module:cloop: invalid argument
mount: Mounting/dev/cloop on /mnt/live/iso failed
cp wont work
no such device
no such file

kernel panic!

no matter if i try to boot it live or live-safe i get the same list of errors, yesterday i tried a new g4 12" and the same thing happened so is not the cd, since i also see the penguin up there and the kernel is loaded.

thnkx k

this is exactly whats going on..i have d/l the no stages live cd..and the g4 live cds 1 and 2...

Please someone give me a clue on what or how can i make those cds of any use?

the partition map is ready on my machine. but i just cannot do a netinstall cause im on a modem connection.

any advice greatly appreciated.

"insmod: init-module: cloop: Invalid argument "

this is the bad line. cloop is a module that is able to loop mount compressed images. Each livecd has such a compressed live environment. insmodding cloop also requires an extra argument (the path to the compressed live environment image). If that path is invalid or null, what happens is illustrated in the posts above.

My guess is that for some reason the cdrom couldn't be mounted/found. I'm writing this from a TiBook 550 (have also tried a 400) on which I was unable to reproduce the problem.

ok thanks for your answer but i dont get why cdrom can be mounted? since i have booted from the cd, and gentoo is supposed to find is way through the cd's files..as said before it didnt work neither on a new g4 powerbook 12". I read elsewhere that its all related with the compressed file initrd.img.gz. The solution was for oldworld macs and it stated booting on another machine, changing some lines in the yaboot.config..but i guess it was a solution for oldworld machines.

so far i have downloaded and tried:

livecd-ppc-1.4-nostages.iso
gentoo-ppc-1.4_rc7-gnome-31.iso
livecd-g4-grp-1.4-cd1.iso

no luck yet.

since im on a modem connection i cannot try netinstall. Though i guess on those 3 cd's i have all i need to get through..only point is i have booted into debian install how can i guide it to the kernel modules on the cds?

thnkx de advance

Mounted the LiveCD on an x86 gentoo box
copied the initrd.img.gz file to /var/tmp
gunzip initrd.img.gz
mount -o loop /var/tmp/initrd.img /gentooCD
modify /gentooCD/linuxrc to add the modprobe lines
umount /gentooCD
gzip initrd.img
copy modified initrd.img.gz to Mac OS X box
burn onto MacOS CD
Boot 6500 into MacOS
copy initrd.img.gz from CD to System folder
Insert LiveCD into 6500 CDROM
BootX (as above)

That got me to the login prompt .

what did i do?

i booted the live CD on my TiBook
i mounted my TiBook HD as rw
i copied initrd.img.gz to my TiBook HD
i gunziped the image
i mounted the image
i edited linuxrc to include these 2 lines:

Code:

modprobe mac53c94
modprobe mesh

i saved linuxrc
i unmounted the image
i unmounted my HD
i rebooted into the Mac OS and copied the uncompressed version of the image to the 9600 HD
i told bootx to use the edited uncompressed image

How did you burn your gentoo cds ? Are you sure they're plain iso9660 ?

double clicking on the .iso image, draggin it to toast titanium window previously set to iso9660...im on toastTi 5.2, os 10.2.6, am i doing something wrong in the process?

is it possible to boot in linux using the old world method of bootX, that way i might get to the cd contents through another path...since in my machine the live cds dont boot? is there another way through?
