I came across this handy information and figured I would pass it on, There are a number of utilities that you will have to upgrade for them to work properly with your new 2.6 kernel. Some of the utilities listed in 'Changes' you won't have to worry about, as for example they may be specific to certain filesystems. However, you will at least need to meet the minimum version requirements for the following (see 'Documentation/Changes' for the latest requirements -- they may have changed!): Name: Minimum version: How to find version: Gnu C Compiler 2.95.3 gcc --version Gnu Make 3.78 make --version binutils 2.12 ld -v util-linux 2.10o fdformat --version module-init-tools 0.9.9 depmod -V procps 2.0.9 ps --version [procps 2.x] [procps 3.x] The following utilities are filesystem specific. If you're running ext2 or ext3, be sure to update your e2fsprogs, if you're running jfs, be sure to update jfsutils, etc... Name: Minimum version: How to find version: e2fsprogs 1.29 tune2fs jfsutils 1.0.14 fsck.jfs -V reiserfsprogs 3.6.3 reiserfsck -V 2>&1 | grep reiserfsprogs xfsprogs 2.1.0 xfs_db -V nfs-utils 1.0.5 showmount --version And a handful of other utilities that you'll want to update if you use them: Name: Minimum version: How to find version: pcmcia-cs 3.1.21 cardmgr -V quota-tools 3.09 quota -V PPP 2.4.0 ppd --version isdn4k-utils 3.1pre1 isdnctrl 2>&1 | grep version oprofile 0.5.3 oprofiled --version If you're going to be running ALSA for the first time, also be sure to visit http://www.alsa-project.org/ to grab the latest alsa-lib and alsa-utils. A working NVidia driver with 2.6 can be found at http://www.minion.de/. Here are a couple of documents that walk you through the specific issues you may run into when upgrading RedHat 9 to the 2.6 kernel, http://www.fearthecow.net/kernel.html and http://thomer.com/linux/migrate-to-2.6.html Kevin Cozens wrote: > At 12:30 AM 12/26/2003 -0500, you wrote: > >> I decided to celebrate Christmas by compiling a version 2.6 kernel. :-) > > > There is more to getting a (b)leading edge kernel running than just > compiling it.

Kernel 2.6 compile: Comaptability?
by pking123-rieW9WUcm8FFJ04o6PK0Fg＠public.gmane.org 26 Dec '03

26 Dec '03

An earlier poster posed what was a good issue: that I ought to check my software for compatability with the kernel. OK, so I try to check, but the compatability list doesn't appear to be in its usual place.

Compiling the 2.6 kernel
by anton-F0u+EriZ6ihBDgjK7y7TUQ＠public.gmane.org 26 Dec '03

Hi guys, Here is how I got 2.6.0 working on my RH9 system: I used the unofficial Redhat kernel source RPMs. I had trouble with the various new module loading utilities (yes, you do need new modinit and modutils), until I downloaded the kernel with apt-get. It solved the dependency problems. Add the following to your /etc/apt/sources.list: # Arjan's 2.6 series kernel repository rpm http://people.redhat.com arjanv/2.5 kernel rpm-src http://people.redhat.com arjanv/2.5 kernel Then do: # apt-get install kernel-source#2.6.0-1.104 or do: # apt-get install kernel-source to get a list of all possible kernel versions. You will find the kernel under /usr/src/linux-2.6.0-1.104. Configure it as you normally would. 2.6 includes new GTK+ and QT based configuration interfaces. Use "make xconfig" for the QT and "make gconfig" for the GTK one. I like the QT configuration tool better. There is no need to do "make dep" any more. Just do: # make all # make install # make modules_install and you should have a "linux-2.6.0custom" or similar entry in /etc/lilo.conf or /boot/grub/menu.lst automatically. Now on the topic of initrd: initrd.img is created automatically during "make install" by the "mkinitrd" tool. See "man mkinitrd" for details. However, I have found that mkinitrd did not work for the new kernel. I don't think it was even created properly, because when I run mkinitrd manually, it fails. I just compiled the drivers for ext3 and reiserfs (my root system) directly into the kernel, and removed the "initrd 2.6..." line from my /boot/grub/menu.lst file for the new kernel entry. I think initrd is only really useful for generic distribution kernels; if you make a custom kernel, it makes sense to compile your IDE/SCSI chipset and root filesystem drivers directly into the kernel. FYI: a new version on mkinitrd came out today on apt-get. Maybe this one will work. If you still have problems with modules not loading, get the new module-init-tools version 0.9.12 or newer. You will have to convert your /etc/modules.conf file to /etc/modprobe.conf format, etc. Read the README with module-init-tools. But first try the apt-get solution above! I hope this helped.
