Hi,

First time attempt to get Gentoo running on G5 PPC64-64ul, the problem is that after config and build the kernel, when I rebooted and selected l from the boot menu, things seem to goes fine until i reach a point:

done
found display: pci@0,ATY,F0000000,TracerParent@0,Tracer_ATY/10, opening .... _

(don't rememeber the exact line, but something pretty close to that)

at this point the screen is in white background with that message and it just sits there.


Here are some step that I did that got me here, hopefully someone can point out what's wrong:

create partitions with mac-fdisk,
/dev/sda2 is boot partition
/dev/sda3 is swap
/dev/sda4 is root with ext3

emerge stage3 64bit userland tarball and portage and copy distfiles
ran USE"-doc symlink" emerge gentoo-sources

then ran make menuconfig, configure ethernet driver support (Intel Pro ones)

make zImage

then copy zImage to /boot/vmlinux
copy System.map to /boot/vmlinux.map

my fstab, I have commented out the /dev/sda2 (boot) and have swap, root, proc and shm in there
for yaboot.conf

I have:

boot=/dev/sda42
device=hd:
ofboot=hd:2
timeout=5
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot

image=/boot/vmlinux
root=/dev/sda4
partition=4
label=Linux
read-only

enableofcdboot
enableofboot

ran mkofboot -v, everythign went fine
exit gentoo environment and reboot and got me to that white screen with that message.

Anyone have any idea what can cause this?
btw I talk with joslwah on IRC, he helped me to get to this point, but told me that other people on the team might have an idea of what's going on.

Thanks.

Is it a PCIE graphics card?
Try booting with the install CD again, and compile one kernel using the CD defaults
Code:
zcat /proc/config.gz > /path/to/a/.configfile

If it works then you can compare both config files and see what's missing. (don forget to backup your oldconfig first.

sorry I'm still new with Linux, what is /path/to/a/.configfile ? I just don't know where to dump out the content of config.gz to so that when I compile the kernel that it will use the config that just dumped out.

can I just do zcat /proc/config.gz > .config?

thanks

to compile the kernel you need a .config file, is usually located on /usr/src/linux, if you want to compile the kernel with the config in /proc/config.gz you need to dump it into /usr/src/linux/.config
