How to get new kernel ?

znavko · February 22, 2018

Hello! I emerged gentoo-sources to try if my Lenovo G50-30 will not freeze suddenly on it.

I do not know where get config for it. I used config from /usr/src/debian-sources dir - last saved config that I think is workable. Is it right?

It compiled, but there is no new kernel in /boot. What to do after compilatioon?

Genkernel provides a generic configuration that works with gentoo-sources,vanilla-sources.

Verify /usr/src/linux is symlinked to the kernel sources to be built:
eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.4.115 *
  [2]   linux-debian-sources-3.19.3
* is pointing to linux-4.4.115 vanilla sources
ls -la /usr/src/linux
lrwxrwxrwx 1 root root 13 Feb 23 23:37 /usr/src/linux -> linux-4.4.115

Command to build:

genkernel all

Genkernel installs my completed build of linux-4.4.115 to /boot

ls /boot
System.map-debian-sources-x86_64-3.19.3-1~exp1
System.map-genkernel-x86_64-4.4.115
initramfs-debian-sources-x86_64-3.19.3-1~exp1
initramfs-genkernel-x86_64-4.4.115
intel-uc.img
kernel-debian-sources-x86_64-3.19.3-1~exp1
kernel-genkernel-x86_64-4.4.115

After configuring grub I reboot into new kernel:

uname -a 
Linux funtoo 4.4.115 #1 SMP Fri Feb 23 22:06:22 EST 2018 x86_64 Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz GenuineIntel GNU/Linux

config-extract is not shipped with gentoo-sources. it is a specific tool that included and works with debian-sources only

znavko · February 22, 2018

genkernel

znavko · February 23, 2018

https://www.funtoo.org/Funtoo_Linux_Kernels Second step: Grabbing a configuration file

# cd /usr/src/linux-4.15.4-gentoo
# ./config-extract
bash: ./config-extract: No such file or directory

in gentoo-sources config-extract is abcent. Can I use /proc/config.gz and how?

znavko · February 23, 2018

okay. How to config kernel when install manually?

My /boot contains lthis

/boot # ls -la

The link https://www.funtoo.org/Building_a_Kernel_from_Source says

Copy configurations if you have previous configurations to copy:
# cp /boot/config-3.13.7 .config

What to do if I use gentoo-sources first time? I have no sense which modules I need and will current kernel config help me or not.

znavko · February 23, 2018

@jhan , please, do you manually choose all kernel parts you need? is there any more useful manual for me?

znavko · March 8, 2018

Thank you @cardinal! Your advise was simple for reproducing. But one question rested.

I run this

''' my /dev/sda1 does not mount itself
# mount /dev/sda1 /boot
# cd /usr/src
# rm linux
# ln -sf /usr/src/linux-4.15.7-gentoo-r1 /usr/src/linux
# cd /usr/src/linux
# eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.15.7-gentoo-r1
  [2]   linux-debian-sources-4.14.12 *
# eselect kernel set 1
# genkernel --menuconfig all
''' then I load last config from linux-debian-sources-4.14.12 and exit menu
''' it compiled kernel and modules
''' and put into /boot dir newkernel

# reboot

I saw new kernel's line in grub during boot, gentoo-sources was default. I got error message during start: wpa_supplicant could not started.

I check lsmod and saw Atheros/Qualcom driver was absent. https://bpaste.net/show/a1aaf108a5fd

This manual helped me to setup WLAN driver on Funtoo https://wireless.wiki.kernel.org/en/users/drivers/ath9k

I reconfigured kernel checking new lines:

Quote

Device drivers -> Network devices -> Wireless LAN ->
* Atheros/Qualcomm devices
M Atheros 5xxx wireless cards support
M Atheros 5xxx PCI bus support
M Atheros 802.11n wireless cards support
* Atheros ath9k PCI/PCIe bus support
M Atheros 802.11ac wireless cards support
M Atheros ath10k PCI support

I just saw `genkernel --menuconfig all` loading debian-sources config and checked all options I found in the other terminal with `genkernel --menuconfig all` (configuring gentoo-sources).

WLAN works.

But I cannot mount /dev/sda1 and `fdisk -l` looks another

# mount /dev/sda1 /boot
mount: special device /dev/sda1 does not exist

# fdisk -l

I think I need configure kernel to work with disks? Which options should I enable?

znavko · March 9, 2018

kernel config is this: `# cat /usr/src/linux/.config | nc termbin.com -t 9999`

http://termbin.com/fwxy

was this `# cat /usr/src/linux-debian-sources-4.14.12/.config | nc termbin.com -t 9999`

I found my new kernel config lacks lot of options in 'Pseudo filesystems' and all other sections. Completely empty config. How to determine which option I need to mount /dev/sda1 ?

# cat /etc/fstab
...
# <fs>			<mountpoint>	<type>		<opts>		<dump/pass>

/dev/sda1		/boot		ext2		noauto,noatime	1 2
/dev/sda2		none		swap		sw		0 0
/dev/sda3		/		ext4		noatime		0 1
#/dev/cdrom		/mnt/cdrom	auto		noauto,ro	0 0

znavko · March 9, 2018

Using Gentoo Handbook https://wiki.gentoo.org/wiki/Handbook:Alpha/Installation/Kernel I made step "Activating required options":

Enabling devtmpfs support, Enabling SCSI disk support, Selecting necessary file systems.

But no effect. I cannot discover which kernel configuration influences on /dev/sda1 could be mounted.

palica · March 9, 2018

znavko what error do you get when mounting /boot ?

znavko · March 9, 2018

# mount /dev/sda1 /boot
mount: special device /dev/sda1 does not exist

I get this error when run new kernel (gentoo-sources) .

I have no such problem in old kernel (debian-sources) .

PS: how to set English for terminal output temporary?

palica · March 9, 2018

anything in dmesg that would help to debug, can you paste maybe the whole dmesg somewhere?

ad PS you have to switch locale to change terminal output

palica · March 9, 2018

did you create or recreate the partition now?

maybe a reboot is needed or use partprobe from sys-block/parted to re-read the partition table.

partprobe -s

znavko · March 9, 2018

no, i am not creating partition. but I used tool from systemrescuecd to restore partitions cause in last installation I needed to save data on disk and clicked accidentally to mkfs... cannot remember details, but that tool helped to restore partitions and now I am using that partition I had before reinstall. so may be this is causing the problem?

thank you for your attention. is it partition table gap?

in a qna site i read about raid and dolvm in grub.cfg. I rebooted to debian-sources to get access to /dev/sda1. if it is useful here my grub.cfg that I did not touch:

I think that your partition table is somehow corrupt (EOD = end of drive) so the partitions are created larger then the drive. I personally would start over from scratch wiping the drive (backing up data before).

# LC_ALL="en" fdisk /dev/sda1

Welcome to fdisk (util-linux 2.29.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device /dev/sda1 already contains a ext2 signature.
The signature will be removed by a write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0xba86f0bc.

Command (m for help): p
Disk /dev/sda1: 128 MiB, 134217728 bytes, 262144 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xba86f0bc

Command (m for help): v
Remaining 262143 unallocated 512-byte sectors.

Command (m for help): q

I hope I have a possibility to write necessary partitions not crashing entire system.

Please, can I prepare disk using https://www.funtoo.org/Install#Prepare_Hard_Disk with that difference that I will not empty partition table with 'o' choice in fdisk tool?

I will only create ext2: from 0 to 128M and swap to 2G. Will my sda3 rest after making this stuff?

the joke is that I got idea my laptop freezes suddenly exactly because of this partition error.

znavko, backup data and start fresh with wiping the partition table, if you can. I don't know how non-destructive it would be to delete partition 3 and recreate it and hope that the filesystem is going to recognize it and be happy about the change. My recommendation it to start from scratch. You have done probably some strange things while creating this partition table. There are tools to manipulate partitions like parted and gparted, but as I've said making a backup and starting again will probably take less time then running some operation on the disk to fix the errors and with unknown result.

Plan for znavko:

backup data
create new partition layout recreating the partitions from scratch
copy data back
done and happy

How to get new kernel ?
