Release Notes for Debian GNU/Linux 3.1 (`sarge'), PA-RISC
Appendix A - Upgrading the kernel


The following instructions explain step by step how to use the available backported tools to install the newer kernel.

Because packages may need to be installed from woody, you should first check that entries in your sources.list still refer to woody as explained in Checking your sources list, Section B.2.

Download and install the needed packages

with apt: to install the packages with apt or one of its frontends, add the following line in your /etc/apt/sources.list:

     deb http://ftp.debian.org/debian/dists/sarge/main/upgrade-kernel ./
     # sources are also available if you need them
     # deb-src http://ftp.debian.org/debian/dists/sarge/main/upgrade-kernel ./

Then install the packages module-init-tools, modutils, palo, and initrd-tools:

     # apt-get install module-init-tools palo initrd-tools modutils

(Afterwards you can safely drop the additional entry again.)

After that change your sources.list file to point to sarge as described in Preparing sources for APT, Section 4.4, update your packages lists and install the kernel-image-2.6.8-2-64 package.

with dpkg: to install the packages directly with dpkg you need to download the necessary files first.

The kernel package depends on module-init-tools (which conflicts with the old modutils); initrd-tools depends on cramfsprogs. All other dependencies (which are stat, cpio and ash) can be satisfied with packages from woody in the usual way.

If you use LVM, you should also install lvm2 before you reboot as the 2.6 kernel does not directly support LVM1. To access LVM1 volumes, the compatibility layer of lvm2 (the dm-mod module) is used. You can leave lvm10 installed; the init scripts will detect which kernel is used and execute the appropriate version.

Don't delete your old kernel yet

You should first verify that the new one boots and all hardware needed for the upgrade works (e.g. network adaptors).

Make your system bootable

You will probably have to adapt your boot loader configuration /etc/palo.conf. Note that the kernel now uses an initrd while the Debian kernels in woody did not.

If you currently use raidtools2, you should read Upgrading from raidtools2 to mdadm, Section 4.6.2 before you reboot.

Reboot to the new kernel
Check your system

Check especially input devices, display devices, devices needed to access the sarge packages (i.e. network adaptors, CD drives, etc). Some driver modules may have been renamed, some drivers which have been compiled into the old kernel might now be compiled as modules, ...
