From: r00f on 24 Jan 2010 17:59 Hallo! I use slackware 12.2 the kernel i use is 2.6.27.7-smp. and i want to compile 2.6.32.5 kernel. It is my first time that i will "play" with this thing and i m little afraid of it.. So..can you make it little friendly to me? Have you suggest me anything or do you know a good tutorial to follow...? Is there something that i have to be careful ? Thanks for any of your answers..!

Main thing is to be sure you can boot the distro kernel. I suggest you ease into running a cuystom kernel by first updating to 2.6.27.44, then creating a custom kernel config, finally update to later kernel version. Skipping from 2.6.27 to 2.6.32 is not as simple as copying old config and running make oldconfig. You need to perform hardware discovery with tools such as lspci, lsusb in order to select the correct kernel drivers for your hardware. Did I mention making sure you don't break ability to boot distro kernel? You may view some .configs and dmesg boot reports from several machines here on http://bugs.id.au/kernel/boxen/ -- current /etc/lilo.conf files are there too, showing how I name kernels and labels so that the distro kernel remains a backup boot option. For example, deltree:/etc/lilo.conf: # /etc/lilo.conf for slackware-11.0 on deltree 2007-01-30 # boot = /dev/hda root = /dev/hda2 read-only compact lba32 prompt timeout = 30 default = 2.6.27.44a image = /boot/bzImage-2.6.27.44a label = 2.6.27.44a image = /boot/vmlinuz-ide-2.4.33.3 label = slack-2.4.33.3 other = /dev/hda1 label = service other = /dev/hda3 label = other # end Grant. -- http://bugs.id.au
From: watnne on 25 Jan 2010 03:29 Go stepwise with your kernel upgrade. First ie 2.6.27.7-> 2.6.29-> 2.6.31->newest.

Well, if you know what hardware you have, and which features you need for your system, it is actually quite easy. I do not understand that people think it is so difficult. In the old days before autodetection of hardware was standard in any OS it was not much more difficult to compile a kernel than to install windows with all neede drivers. My first was on Slack 3.6 or something loooong time ago. The most important thing to remember when compiling a new kernel, as others also have said in this thread, is to add it as a separate entry in Lilo / grubb. Then you can boot back to the orignal system and make another attempt if someting goes wrong. Then you will only loose some time, not your entire system. Before you start, make a list of all your hardware, 'lspci' and 'lsusb' is your friends here. Try to find the makers of the chips on your hardware, not just the brandname. Think of what your system neees, are you running multiprocessor, server, laptop etc, raid etc? There is noe use in having RAID 5 support on your laptop, or battery support on your desktop. Ideally you only add support for what you need, in practise (from my experience) I add a bit more because of "nice to have" thinking. Do some consideration on what you will compile as modules, and what you integrate into the kernel. Everything needed for booting you system should be in the kernel, and personally I like to add all permanently installed hardware to the kernel. Then you should just start, and try. If you do good preparations you should probably end up with a kernel that at least boots your system, but when you do it for the first time you should expect to do some attempts before all hardware is up and running. Be prepeared for a lot of google searching, testing and not least the pure joy of finally runing on a kernel you have compiled. Good luck! -- Ole
