 |
|
Whenever I try to boot, I see "Loading Linux linux-4.4.6 ..." and nothing happens.
Why is this happening ?
How can this be fixed ?

You could chroot into your system and set /etc/rc.conf to rc_interactive="YES".
Then reboot and hit the i button when rc starts. Then go step-by-step. |

| The problem is I can't even get openrc to start. Booting stops after "Loading Linux linux-4.4.6 ..." message appears. |

Go to http://sysresccd.org/ and burn it on a CD or USB stick.
It should be able to boot your system (hopefully). |

Then boot from your live USB, follow the steps in the handbook to mount your Gentoo disk, then chroot into it.

Yes, then you use the live usb to get to logs, reinstall kernel and so on before trying to boot again.

1. What logs do I need to get ?
2. What options do I need to enable or disable in kernel ? |

somethin,
The kernel never decompresses. Your last message is provided by grub.
The implication is that grub jumps to the start address of the kernel and the kernel is either
1. not there.
2. not built to run at that address
3. not self relocating.
Hmm, maybe its not even a kernel that gets loaded.
Post your grub.cfg file.
Post the output of
Pastebin your kernel .config file.

I would also add the contents of /etc/fstab and the output of
| Code: |
sudo fdisk -l /dev/sda
|
Change sda for the driver you have your system installed. If you are using multiple disks, then please post the output for each one.

livedvd can boot only livedvd. sysresccd has the option | Code: | | 5) Boot an existing Linux system installed on the disk |
This is sometimes very helpful for fixing mbr/bootloader/kernel problems. |

I found out that problem is with frame buffer drivers. If I enable only efi frame buffer I can see the output (The kernel config in http://pastebin.com/T5mBxW5v has only efi frame buffer), but if I enable nvidia framebuffer I don't see the output.
How can I enable nvidia frame buffer and be able to see the output after "Loading Linux ..." ? |

somethin,
You must not enable nvidia frame buffer.
When you do, nvidia frame buffer grabs the video cand and neither nouveau, nor nvidia-drivers will work in Xorg.
The nouveau kernel driver includes a framebuffer console. nvidia-drivers will give you dire warnings about any attempt to use a framebuffer driver of any sort.
Simple Framebuffer and on EFI systems, with EFI in use EFI framebuffer may work. A few years ago, vesa frambuffer worked too.
The trick with mixing nvidia-drivers with a framebuffer console is that the framebuffer driver must not attempt to change the video settings.
