Thx man! do I need to comment the old kernel? don't want loose it if some goes wrong...

what about /boot? btw I don't have it...

john-doe,

Leave your old grub entry. With your present settings grub will give you 5 seconds to choose it from the menu.
You must have a directory called /boot. It could be a partition too but need not be.

why SO PAIN every upgrade of kernel :?:

??

I'm getting now why win$UCK$ is used 4 thousand of millions...

Probably because people like blue so much better. You have a working kernel, which is a good thing to fall back to. Learning to properly configure the kernel takes time. Read, think, configure, compile, install, try, repeat. :wink:

In the reading category, the kernel says couldn't mount the root. It tried several filesystems. Is the one you actually have among them? What root filesystem do you have?

Just to make sure, your working kernel is one that you configured or is it a Genkernel-made "kitchen sink" kernel? Once you've successfully configured one kernel, you can often copy that configuration file to the new kernel source directory to use as a starting point. This is explained in the Gentoo Linux Kernel Upgrade Guide, Section 11.

Let me get back to penguin(writing from winBUG$) to show U grub.conf

EXT4

John R. Graham · Posted: Wed Jun 13, 2012 10:29 pm Post subject:

Don't believe I need to see grub.conf. It seems clear that the drivers for the Ext4 filesystem were omitted from the kernel when you configured it. Make that change, recompile, reinstall, and let's see what happens.

Gentoo is an all volunteer organization, depending on its user's support to evolve and improve. All Gentoo developers, council members, board of trustee members, and lowly forum moderators are unpaid volunteers. The somebody that should do something is you. Your part here, as a member of the Gentoo community, is to file a bug in Gentoo Bugzilla, citing the documentation that's in error and (if possible) the correction that needs to be applied.

@john-doe, if you don't understand something, please just ask for clarification. We don't mind. :wink:

If you don't want to do something that we suggest, then tell us why and we will clarify. But jumping around from method to method and thread to thread is actually making it harder on yourself.

NeddySeagoon has given the same advice that I did. This is actually a pretty simple problem. Are you able to try that advice?

John: U will not believe this:
tried to install new kernel ==> 3.4.3 but 'to vary' some error on kernel: config devtmpfs so = = > NO KEYBOARD NO MOUSE!

the ordeal ... :evil:

You mean you got the new kernel to boot but you don't have a keyboard or mouse inside the desktop environment?

Yep! some related to UDEV or so...

same thing: https://forums.gentoo.org/viewtopic-t-923956-highlight-.html

John R. Graham · Posted: Wed Jun 20, 2012 12:56 am Post subject:

No, not related to udev. When you build and run a new kernel, you need to rebuild the kernel device drivers that are not part of the kernel source tree. Prominent examples of these out-of-kernel drivers are: xorg-drivers and nvidia-drivers.

Are you by chance running Portage 2.2? There's a useful feature that helps rebuild the correct packages in Portage 2.2.

Also, are you starting X automatically on boot (and thus you have no keyboard at all) or are you still starting it manually with startx?

Finally, don't go off and try something else. Let's debug this issue one step at a time, methodically, until we get it solved. Deal? :wink:

how do I get .config file?

John R. Graham · Posted: Wed Jun 20, 2012 3:10 pm Post subject:

I don't understand the question. Could explain a little more thoroughly, please?

Also, could you answer my previous questions? It's pretty hard to help you if you don't give us what we need to know to help you.
