Hello everyone,
I've been attempting to set up my system with Gentoo. Being a Linux-noob and trying to learn as much as I can, I already ran into quite a few troubles. The problem I'm about to confront you with, I couldn't fix on my own, so I hope that you can help me!

First of all some Info about my system.
My lspci: http://ix.io/19kR
My .config: https://bpaste.net/show/c408804bf52a
My grub.cfg: https://bpaste.net/show/c408804bf52a
My fstab: https://bpaste.net/show/136631b14f75
My make.conf https://bpaste.net/show/0510b534c256

I configured my kernel using the command "genkernel --menuconfig all", and - according to my lspci - I think i selected all the necessary driver-options.
When I try to boot up my system however, i get this green-screen:

Now after doing quite a bit of research, I still can't get around this problem, so I decided to write a forum-post here.
Really hope, someone can help me locate the problem, so I can finally boot my machine!

Cheers :)[/code]

I'd run smartctl test on your hard drive.

Tomogui,

The result of that test are stored in the drive. To see them use
Code:
smartctl -a /dev/sda


While that's interesting, its probably not your issue. Your kernel has several drivers configured for your video card.
Thats a bad thing. Normally when you configure several drivers for the same piece of hardware they all fight it out, none of them wins and the hardware does not work. Its usually harmless to the hardware.

Looking at your kernel, you have
Code:
CONFIG_DRM_NOUVEAU=m
Thats a good choice for your nVidia graphics.
The
Code:
 CONFIG_NOUVEAU_DEBUG=5
CONFIG_NOUVEAU_DEBUG_DEFAULT=3
CONFIG_DRM_NOUVEAU_BACKLIGHT=y
go with it, so leave those alone too.

The nouveau kernel driver gives you a free console framebuffer driver too. So all the hardware framebuffer drivers in the kernel menu
Code:
#
# Frame buffer hardware drivers
#
must be off. In particular
Code:
CONFIG_FB_NVIDIA=m
CONFIG_FB_NVIDIA_I2C=y
CONFIG_FB_RIVA=m
must be off. They are for very old, and even older nVidia cards.

Rebuild your kernel. in the menuconfig step turn off all the hardware framebuffer drivers. Press / and enter FB_NVIDIA to find your way to the menu.

Reboot to test.

Hint: before the reboot, run
Code:
uname -a
Make a note of the kernel build time shown.
Reboot and run
Code:
uname -a
to make sure you are actually using your new kernel.
Many beginners and even old hands mess up the kernel install from time to time. The result is that you can fix your problem and not know it because you still boot the old kernel.

NeddySeagoon,

you think ACPI SECURITY FREEZE LOCK is harmless?

Buffoon,

Not if it gets triggered, no.
I didn't spot that. Well caught!

NeddySeagoon!
Thank you so much for looking into my problem! The changes you suggested worked out! I finally managed to boot the system :) This is a huge relief.. I think I already spent around 30+ hours on this, having to constantly recompile my kernel, trying out different settings. :D
