Problem installing Gentoo, boot error

I attempted to install Gentoo (AMD64 install), but some problems occurred (first-timer here, btw

).

I did everything by the manual, partitioned my HDD, had to manually compile the kernel (couldn't compile it with genkernel for some reason), installed GRUB. The problem is when I choose Gentoo from the GRUB menu, it won't boot.

Here is the error I receive:

This typically means that you didn't include the driver for your hard drive controller in the kernel. Please boot up in the install CD and post the output of

Hi laci,

Can you provide further information like:
1) /boot/grub/grub.conf
2) /etc/fstab
3) Make sure that if you have compiled your SATA AHCI driver into the kernel rather than modules
4) Set your filesystem support in Kernel
5) Make sure your system is compiling the kernel with the config that you made

I have recently encountered similar problem as yours, lucky to receive the help from the ppl in this forum, and finally found myself making the 5th mistake, which is I like to save the kernel config into an alternative file (e.g. 123.config) But when I run make && make modules_install, the system would just take the .config to compile the kernel. Hence even I made the changes to correct the mistakes I made, it's still running the old .config. (how stupid I am)

You may take a look of my previous post, which maybe useful to you as well.

ronstudio,

I posted the /boot/grub/grub.conf and /etc/fstab files in my first post. I have noticed that I didn't compile the JMicron JMB36x driver into the kernel, so I changed that. The filesystem drivers are also compiled into the kernel, I checked that. I also read the topic you told me to read, I have enabled CONFIG_SATA_AHCI_PLATFORM, but I still receive the same error message. I don't have any other ideas what to do. Thanks for your help, though.

DONAHUE,

I have made the changes you told me, and I still get a kernel panic

The kernel booted does not appear to be the kernel recompiled. Need to investigate.
Boot cd,

DONAHUE,

I checked the date times of the recompile and recopy and they were OK. There was a 3 minute difference (the .config I used 31 August 12:58 and the /boot/linux-2.6.39-gentoo-r3 31 August 13:01).

This is the wgetpaste of the .config I used (the .config file is /usr/src/lacikernel2modification.config): http://paste.pocoo.org/show/467900/

lspci -k | wgetpaste : http://paste.pocoo.org/show/467916/

wgetpaste /proc/mounts: http://paste.pocoo.org/show/467912/

fdisk -l | wgetpaste: http://paste.pocoo.org/show/467914/

Thank you for having patience with my problem.

Sorry for the confusion I made, http://paste.pocoo.org/show/467900/ is the result of wgetpaste /usr/src/lacikernel2modification.config

When I downloaded a kernel seed from kernel-seeds.org, I loaded it in makemenu, made my changes, and then saved it as
/usr/src/lacikernel2modification.config I thought it should compile the kernel with it.

The hard drive which I am installing Gentoo on is an internal Western Digital 160GB, the model is WDC WD1600JS-41M and the hard drive controller is set to AHCI mode in BIOS.

This is the result of lspci -k:

laci92,

if you used options DONAHUE posted earlier, built a kernel and installed it properly you would not get unknown-block(0,0) error.

Are you sure you used kernel .config file you thought you were using? Note, make menuconfig will not load your custom-named conf unless you do it manually.

I finally managed to solve the problem. DONAHUE and Jaglover, you were right, it seems that menuconfig did not use my .config file. I solved the problem by copying my .config file, /usr/src/lacikernel2modification.config, to /usr/src/linux and then renaming it to .config . Then I compiled the kernel, copied the bzImage to /boot, rebooted, and I was greeted with a login prompt

Thanks everyone for your help, I'm shamed because of this stupid error I made *headdesk*

You made an interesting problem. Thanks.
