Gentoo Kernel dont find root acer cloudbook11


Hi,
Gentoo kernel generated with genkernell, do not find root.

Fstab is correct.

The notebook is Acer cloudbook 11, Celeron n3050 2gb ram e sd/mmc 32gb

When I install arch in legacy mod I have to add "edd=off noapic" to let boot, there is something that I can add here to let gentoo kernel see root partition?

I cannot change SATA interface, and I don't know how to compile kernel that can see /root, because I don't know why it do not work.

I dont' remember the sintaxis but it was tell me "kernel cant' find root on uuid...." and it was the right uuid. one thing that I have noticed is that "gentoo hibrid live iso" (the complete version, in fact I have booted with the small one) don't see my sd/mmc, so I suppose that genkernel don't have the rght parameter to load the mmc.

nothing change if I put /dev/mmcblk0p3 or the uuid

How do you know it was the correct UUID? Are you booting off of a USB drive? Is this the installation media?

But you don't know what the UUID of the root partition actually is. And you're not really answering the questions I've asked. So, I have no idea what's going on with your system.

When the grub menu appears you can hit 'e' and edit the linux line and delete what comes after root= and replace it with the device file of the root partition, i.e. /dev/sda. Then hit CTRL-x to boot the system.

Hi awesome and thank u for trying understand my problem. But actually I have done all that before ask in this forum. And I have tried both /dev/mmcblk0p3 and uuid from grub line and tried some string like "dousb dscsi noapic edd=off"

Yes, I don't know how to explain myself, don't even speak English in the right way.

The last thing that I kwno is that even the sabyon kernel can't boot.

The problem with genkernell was the same. Here a picture.

At the prompt, type 'shell'. Then type 'ls -al /dev/disk/by-uuid' and post the output.

Cant do that, I dont have anymore the installation.

But it's sure that uuid was correct, just like was correct /dev/mmcblk0p3.

From shell i tried even to write

"set_root={" and press tab to see my option.

So the only thing that can help me is to understand what module or integrated thing is used by kernel on this notebook to boot, because all linux distribution (arch and debian) boot from this sd/mmc.

Bytheway redcore linux have a custom kernel that boot.so I will investigate that.

Thank u for your help.
Goodbye

All kernels are made for booting. There is nothing in the kernel that specifically enables or disables booting. I'm sorry you're having problems. Let us know if you need more help.
