Re: New kernel needed for potato upgrade?

They're separate issues in the main. What you have to be careful about
is that you don't accidently upgrade packages that are related to the
kernel rather than the distribution, e.g. pcmcia stuff.

2.0.x kernels have route commands in /etc/init.d/network whereas
2.2.x kernels set them up automatically already so the redundant
commands produce the error messages. Ignore them.
http://www.uk.debian.org/releases/stable/running-kernel-2.2
has a reference to a slink-compatible version of netbase suitable
for 2.2.x kernels.

If you're back on 2.0.x, just check that /etc/conf.modules is correct.
This file used to be maintained by you, but is now built from
/etc/modutils/* which is the same stuff but distributed across
several files so that you only have to maintain your bits,
principally local.

No idea. "Not working" doesn't help. But you can check that any modules
you need are loaded by comparing /etc/modules with /proc/modules.
Bear in mind that /etc/modules needs checking if you change kernels,
particularly anything involving stock kernels. (If you compiled
your own 2.0.x and 2.2.x with the same flavours (as I do), there may
be no changes required.)
You will probably notice that kerneld is replaced by kmod and that
automatic rmmod'ing is done differently (by a cron every 20 mins).
