Posted: Thu Oct 17, 2013 11:51 am Post subject: Installing Gentoo with Intel N-7260 Wireless chips |
|
|
Hello,
I'm currently trying to install a gentoo on my new laptop, a Sony VAIO SV-P1321C5E.
I've already windows 8 installed and do not really want to get ride of it right now.
I'm booting from a gentoo liveusb that I've made according to the gentoo documentation, the kernel is a 3.8.13 kernel.
The probleme I have is about my wireless network.
I've downloaded the ucode iwlwifi-7260-ucode-22.0.7.0.tgz (from http://wireless.kernel.org/en/users/Drivers/iwlwifi) but, according to the site, it's only valid for 3.10+
Is there any gentoo live image with such a kernel (>= 3.10) ?
I haven't really understand how those ucode are working ? What is the module name ? iwlagn ?
So, once I will have my gentoo live cd booted, with a kernel 3.10+, the only thing I need to do is to copy the *.ucode file in /lib/firmware and do a:
modprobe iwlagn (iwlwifi, others, ???)
Thank you for any advises that comes into your mind |

The module is named iwlwifi.
Have you tried the Gentoo livecd already? Perhaps it works with kernel 3.8, too.
For installing Gentoo you can choose any linux that has the same bitness (32 or 64) as your desired installation and that allows you to use "chroot".
So you can use linux mint, ubuntu or Suse live cds.
A favourite amongst Gentooers is the SystemRescueCD, which is based on Gentoo (http://www.sysresccd.org/).But it seems to come with a 3.8 kernel, too. _________________ Kali Ma

I've tried the 'install-amd64-minimal-2013????.iso' (not sure of the date ... but it was a 3.8.13 kernel)
And yes I've tried to install the ucode on the 3.8 kernel, but it does not seem to work.
I will download the last install-amd64-minimal-20131010.iso first, and redo my USB bootable device and try again.
I try again the ucode installation process, and I will come back to you. Perhaps I've made something wrong as it's the really first time I should do this kind of stuff for a gentoo installation.
Thank for the reply
I will surely post some others question on this thread later |

Hello,
I then tried SystemRescueCD and it works just fine. I load the iwlwifi module, the lspci command show the right info:
01:00:00 Network controller: Intel Corporation Wireless 7260 (rev 6b)
But I do not see any interface in /sys/class/net excep "l0" ?
Loading the module is not enougth in order to have a new "wlan0" (or any other name) here ?
Any idea ? Help ? thanks |

Could not achieve to have the ucode loaded !
Is there a way to tell explicitly the ucode to load with a kernel module ?
lspci -k does not show any kernel module associated to my Network Controller:
01:00:00 Network Controller: Interl Corporation Wireless 7260 (rev 6b)
Subsystem: Intel Corporation Dual Band Wireless-N 7260
If I ran a modinfo:
modinfo iwlwifi
...
firmware: iwlwifi-7260-7.ucode
...
And the ucode is in the /lib/firmware directory
-rw-r--r-- 1 root root 682892 Sep 18 17:13 /lib/firmware/iwlwifi-7260-7.ucode
May I install gentoo without network ??
Thanks |

|
|
Ok .. i've tried to compile the kernel 3.11 in order to see if firmware will be loaded or not, but it does not seem to compile when chroot to tha /mnt/gentoo with a stage3 tar ball untar.
Compilation failed with: bc not found ! (when trying to BC kernel/timeconst.h)
Does someone know which option in the kernel I should disable in order to compile it or not ?
Otherwise, I will try to download bc and try to compile it ...
Thank for any aswner |

|
|
Hello,
back again on this subject, still I do not succeed in installing gentoo on my laptop:
Quote: | Unless you mean that you will install sys-devel/bc, there is an easier way to get bc installed on your system. |
Which one ? I'm not able to run "emerge-webrsync" as I do not have network. So I could not do an "emerge bc"
But anyway ... I boot ubuntu live CD with a 3.11.6 kernel and now, I ve got network and can try to install gentoo from there.
I've download/configure and install my 3.11.x kernel but when I'm booting, I get this kernel panic:
Code: |
VFS: Cannot open root device "PARTUUID=77cdde5d-8c59-45f6-9516-159334b67741" or unknown-block(0,0): error -6
Please append a correct "root=" boot option: here are the available partitions:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
|
The PARTUUID=.... is the one given by "blkid"
Kernel Options:
Code: |
CONFIG_EFI_STUB=y
CONFIG_EFI_VARS=y
|
I'ven't tried "root=/dev/sda7" as I've read this is not valid for GPT disk.
My root partition is in EXT4 and EXT4 is built-in in the kernel
And I do not use "initramfs"
Edit: I trying to boot in UEFI. I've just replace the 'bootx64.efi' with my kernel /boot/vmlinuz....
I will install any grub2, whatever bootloader later, once my kernel will boot.
Do you have any idea ? |

Have you included support for JBD and JBD2, also make sure that your boot partition is also ext4 (not ext2 or ext3), if it is, check if you have added support for them too.
Then, you can generate grub configuration grub-mkconfig -o /boot/grub/grub.conf (or grub2-mkconfig if you have grub2)
I have also GPT disk and works fine for me. |

YOUPI !!!! I'm now able to boot !!!!!!!!!
Do not ask what I've changed in my kernel, I do not know. But I've tried to add as many things as 'build-in' instead of 'module' (such as ahci, SSD driver,etc)
But now .... I do not have any keyboard!
Could you help me ? What kind of option should I add ? Where are the keyboard option in the kernel configuration menu ?
Please, do not ask for any dmesg stuff
Thank for any help |
