Hello,
I am having an issue with my new install, I did my first reboot, and it stops in what looks like a kernel panic. Nothing is being logged yet, so all I could do is capture a screen shot with my camera. I took a video as well and stepped it up to that point when it crashes and there is no errors leading up to it. Anyways, here is the shot http://imageshack.us/photo/my-images/210/screenshot1lh.png/
I am running amd64,
Asus Maximus formula III
Core i7-930
16gb of ram
Radeon 7970
Regular seagate 7200rpm 500gb hdd

Thanks alot, havent been in the game for a while, so if I missed anything.. well you know.

problem is kernel, recommend htpp://www.kernel-seeds.org
if you want outside look:
boot cd, mount gentoo partitions, enter chroot, nominally:
Code:
mount /dev/sda3 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
cp -L /etc/resolv.conf /mnt/gentoo/etc/
mount -t proc none /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) $PS1"
Then
Code:
emerge wgetpaste pciutils usbutils
emerge --info | wgetpaste
wgetpaste /usr/src/linux/.config
wgetpaste /proc/cpuinfo
lspci -k | wgetpaste
lsusb | wgetpaste
wgetpaste /etc/portage/make.conf
gcc-config -l | wgetpaste
and post url's returned

grub conf

I have a genkernel entry in there because I wanted to see if it would work, and it does boot, but it doesnt have net for some odd reason, amongst other errors, so I am removing it in the livecd env.

Thanks in advance for any info you guys can give me, I used to be pretty good at this, but my couple years off have made me sorta slow in the ways.

The following steps should provide a kernel that boots made by importing a basic kernel configuration from kernel-seeds.org and adding needed drivers found in lspci -k.
boot cd, mount gentoo partitions, enter chroot as before, then
Code:
cd  /usr/src/linux
make clean
make mrproper
wget -O /usr/src/linux/.config http://bpaste.net/raw/73460/
make menuconfig
look around, check that File Systems contains enough choices for your needs. Using ext4 for ext2 and ext3 is preferred and selected. When ready exit menuconfig saving the copnfiguration.
Code:
make && make modules_install && make install
ls /boot
nano /boot/grub/grub.conf
the kernel line must use the exact spelling of the new kernel, presumably
Quote:
kernel /boot/vmlinuz-3.6.11-gentoo root=/dev/sde3
If you prefer to copy the new kernel as linux and use that name in the kernel line, feel free.
this kernel is intended to use the manufacturers video driver variously called fglrx, ati-driver, and catalyst. Setting VIDEO_CARDS="fglrx" and INPUT_DEVICES="evdev" in /etc/portage/make.conf and emerging xorg-server after the first reboot followed by running aticonfig --initial should get X ready to run with the manufacturers driver. hal is severely deprecated, suggest removal from USE in make.conf.
Code:
 eselect profile list
eselect profile set 13
assuming [13] default/linux/amd64/13.0/desktop/gnome is the choice for gnome.

Thank you for the information I will try what you suggest and post back, I'm remembering more about the process as I go but will take some time until I get familiar again.. used to be able to get a system up without the handbook lol.

Thank you for your help Donahue, that did the trick!! I have 0 errors on boot, I did hit a snag where it panicked and said vfs root not found, but I found out that the kernel sees the drive as sdf instead of sde when its outside of the livecd environment (??) but no biggie.
Once again, Thanks alot!!

good work tracking the device name change. Remember to keep an old working kernel around until a new working kernel is proven and have fun making changes to get to the kernel you really want.

Always do, I used to use love-sources, not sure if thats even around anymore, but it was pretty bleeding edge and would leave me unable to boot sometimes, learned quick to keep standard kernel around, and make sure to test that it still works after major system package updates.

Thanks again!
