Very Computer

Greetings,

I recently installed the 2.4 kernel on my Red Hat 6.2  machine.  The
kernel seems to boot fine, but there are a few bugs I need to work out.
Here is a sampling of error messages greped from /var/log/messages  that

occur during system boot up...these concern me.

The third line I find curious.  It is as if a map to the modules isn't
loaded...

Jan 13 18:49:42 Taltos kernel: Loaded 15012 symbols from
/boot/System.map-2.4.0.
Jan 13 18:49:42 Taltos kernel: Symbols match kernel version 2.4.0.
Jan 13 18:49:42 Taltos kernel: No module symbols loaded.

Obviously, the error lines are disturbing...

Jan 13 18:49:09 Taltos sysctl: net.ipv4.ip_forward = 0
Jan 13 18:49:09 Taltos sysctl: net.ipv4.conf.all.rp_filter = 1
Jan 13 18:49:09 Taltos sysctl: error: 'net.ipv4.ip_always_defrag' is an
unknown key
Jan 13 18:49:09 Taltos sysctl: error: 'kernel.sysrq' is an unknown key

All of these lines concern me. What is nls and why is there no devpts?

Jan 13 18:49:10 Taltos modprobe: modprobe: Can't locate module devpts
Jan 13 18:49:10 Taltos mount: mount: fs type devpts not supported by
kernel
Jan 13 18:49:10 Taltos modprobe: modprobe: Can't locate module
nls_iso8859-1
Jan 13 18:49:10 Taltos modprobe: modprobe: Can't locate module
nls_iso8859-1

Hhhmmm...

Jan 13 18:49:45 Taltos modprobe: modprobe: Can't locate module
char-major-14

I've recompiled the kernel, checking my configuration to see if there
are an crucial options I missed which may relate to any of these
errors.   But my configuration seems decent...

I've also tried to figure out how devpts relates to the 2.4 kernel, but
I had trouble finding documentation related to this issue.  What is
different in 2.4 with devpts? I had no problem with my previous
2.2.14-5.0 kernel...

For some reason, modprobe can't find necessary modules.  Is this related

to the  "No module symbols loaded." error in the first sample of
output?  My modules make & install seemed to go fine during the kernel
build.

Any insight into these errors would be helpful.  This is my first kernel

compilation, so please bear with me :)

Thanks in advance to all who reply.

The messages printed tells you that no modules were loaded.
I suggest you take a look at what is in the /etc/modules.conf. I noticed
the structure of the modules directory /lib/modules/2.4.0/ has changed
a bit between the 2.2 release and 2.4.
The default behaviour (paths etc) of modprobe and depmod made it
neccessary for me to add these paths by hand in modules.conf to get
tings working again.
This can also be done conditionally depending on what kernel you are
running so you can keep the same modules.conf file even if you have an
old kernel installed on your system and run it sometimes.

The first and most obvious thing is: Did you upgrade your modutils etc before
installing?  I'm 100% sure about your specific errors as I am still getting
my head around things as well, but it is possible this would cause these.

Read the Documents/Changes file to make sure you are completely up to date,
especially if your coming from a 2.2 kernel.
