[SOLVED] ck kernel and i/o scheduler

trixrabbit · 2013-06-20 19:03:51

Hi, I just finished my fresh re-install and I wanted to use ck-core2 like I was using before and NOOP i/o scheduler.
1) I added [repo] in my pacman file, updated my system with pacman -Syu and then installed linux-ck-core2 and linux-cd-core2-headers. But it doesn't seem to have updated my kernel. I'm not sure how to verify this but when I open a console alsi prints my kernel and it's still the 3.9 ARCH.

2) I tried to change to NOOP at boot by adding : APPEND root=/dev/sda1 ro quiet splash, where /dev/sda1 is my /root partition and I couldn't boot after that, I was getting a boot error and I could typpe stuff after BOOT :
I simply removed the line by booting on usb

any suggestions, thank you

1) You need to regen your grub config as it seems you have both the ck and ARCH kernels on board (which is fine).
2) See the wiki page for help (adjust for noop): https://wiki.archlinux.org/index.php/Li … _Scheduler

thank you I had already read that many time but it lead me to some other forums.

I added :

 LABEL arch-ck
	MENU LABEL Arch Linux-ck
	LINUX ../vmlinuz-linux-ck
	APPEND root=/dev/sda2 ro elevator=noop
	INITRD ../initramfs-linux-ck.img

to my /boot/syslinux/syslinux.cfg and now everything boots fine.

Glad it's working for you.
