HowTo: Installing and using KernelCheck

[TheForumTroll]

Really nice program you've made here. I just found it and it's doing its magic right now. Can't wait to see if it works out in the first try with all the tweaks I made to the config. Thank you

Thanks for your hard work I have two questions:
1) Kernel.org shows that 2.6.34 is a stable version of kernel, why don't I get to compile that one? just 2.6.33.5

2) Is there tips for a Nvidia Ion based system, with Atom 330. (I have a Giada Cube N3).

I've tried installing the candela kerneltwice. First time with defaults, second time with the deprecated IDE/SATA support checked on. Both times I run into a kernel panic and recovery mode suggests problem with the root init

If it try to update-initramfs I get a modules not found error.

sudo update-initramfs -c -k linux-image-2.6.34.1-candela 
update-initramfs: Generating /boot/initrd.img-linux-image-2.6.34.1-candela
Cannot find /lib/modules/linux-image-2.6.34.1-candela
update-initramfs: failed for /boot/initrd.img-linux-image-2.6.34.1-candela

This is the contents of /boot showing a missing initrd.img for candela kernel

Putting this out there helped me solve this I hope.

Cannot find /lib/modules/linux-image-2.6.34.1-candela

should have been a clue

I cd'd into the /lib/modules/ and found my problem "linux-image" is not part of the initramfs way of doing things.

Correct syntax should be:

 sudo update-initramfs -c -k 2.6.34.1-candela

[afrodeity]

well, that only solved the "update-initramfs" modules not found issue. It still wants me to append a root, but grub is supposed to pass a "root=UUID=xxx" parameter. Anybody know what is going on and how to fix?

Kernel panic not solved.

UPDATE: I'm going to guess and say I have to run update-grub as well? See you next boot.

SOLVED --- update-grub did the trick, guess the kernelcheck script is slightly out of date.

I have a similar error, my copy of KernelCheck Lumen right now can't find the latest stable 2.6.35, it just tells me that the latest kernel patch is 2.6.34 with the latest prepatch being 2.6.34.2 .

How can I "force" KernelCheck to "find" v2.6.35? Is there a problem with the kernel.org source URLs again?

Hello,
Download 2.6.35 kernel and save to /usr/src
Choose Custom ==> Old stable patch as 2.6.35 in KernelCheck

Compiled 2.6.35 using KernelCheck Old Stable patch method with modified config for my laptop
Working very well so far (1 hr old)
Trying to fix === Wireless issues

EDIT: BTW my Core i7 4 GB RAM HP dv6 laptop compiled and installed kernel in 20 mins flat with -j16 flag
No Turbo Boost working

Also, kernelcheck doesn't create any initrd images. So, make sure to create one before reboot using these steps: 1. cd /boot
2. sudo mkinitramfs -o initrd.img-kernel.name kernel.name

arghh, I am so jealous of you.

Appears that KC is broken now that 2.6.36 is stable. Anyone found a workaround?
