Very Computer

Yesterday I downloaded the file 'linux-2.0.21.tar.gz' and started to
upgrade my kernel from 1.2.13 to 2.0.21.  Everything seemed to go
ok but now when ever I boot up, I get the following error message:

**********
Loading the iBCS module...
Error: The module was compiled on kernel version 1.2.13.
       This kernel is version 2.0.21.  They don't match!
       Check that the module is usable with the current kernel,
       recompile the module and try again.

       Trying to load anyway...
kfree_s undefined
create_tables undefined
current undefined

Failed to load module!  The symbols from kernel 1.2.13
don't match 2.0.21.
**********

Another thing I noticed was that pppd no longer works with the
new kernel.  It gives me an error message something like 'ppp not
supported'.  

Does anyone know what I need to do to fix these problems.

Thanks in advance,

Martin

P.S. On the plus side, I got my sound card to work with the upgrade.

Christ, RTFM, there's a nice little file in the kernel source, it's
called Documentation/Changes

Read it.

Do what it tells you.

Simple eh?

Jose,
  At least for ppp, you need to get the newer version of pppd, 2.2.0f or
higher.  It works with kernel versions above 2.0.something.  (I just
upgraded, but don't have any loadable modules.  You might try
re-compiling without the loadable module support and see what happens?)

Try re-compiling the module once you have your new kernel installed.  The
interface could have changed, and it could be that it does some version
checks.  This usually happens when you grade from one level to another.  

        Trying to load anyway...  kfree_s undefined create_tables undefined
        current undefined

interface problems?  If you have to know the*details, then subscribe to
the kernel-hackers list.  It's very busy, be warned.

No surprise here.

        kernel.  It gives me an error message something like 'ppp not
        supported'.

There are a few changes, but definitively for the better.  This is mainly in
the scheduler (that's why you need to get a higher procps package, and
improved networking [finally!]).  Compile ppp as a module, run kerneld (whacky
kind of thing) and, above all, read /usr/src/linux/Documentation/Changes.

Before I forget... No, you don't have to wipe your disk and install everything
from scratch.  Everything && more than you need to know is in the file
mentioned above.  Wiping your disk for a kernel upgrade is *.  You will
regret the day if something goes wrong (which is usually the case, even when
you backup, something is always misteriously missing...and if you use tar,
then you have to pray hard that you copies remain intact).

Thus, upgrade your stuff manually.  Only upgrade when you know that you need
the features of the new package.  Versionitis does not pay off.  I've been
doing so for 4years now and have rarely experienced unsolicited trouble.  But
then again, if you have no data or work to loose, you might just as well zap
everything...

The choice is yours.

Does this help a little?

Happy Hacking!

Upgrading just your Linux kernel from 1.2.13 to 2.0.* is a no no.
It can't be done that simply.

There is a file you will have to read:

   /usr/src/linux/Documentation/Changes

This will contain the minimum lever utilitiese you have to have on all
your Linux system

   ftp://ftp.wcs.com/pub/freeware/linux/update.linux/

that does a COMPLETE system upgrade.  It has been put together to
allow you to upgrade to kernel 2.0.18 and ALL the other necessary
other bits as well.

The only probelm I really had was the 2.0.18 kernel that was provided
in the upgrade wouldn't boot on my PC.  I booted of my old
1.2.13 kernel and compiled a new 2.0.18 kernel that suited me.

*** If you do this, just make sure that you have a working BOOT disk
that will get you out of trouble ***

I just went from 1.2.13 => 2.0.22 .  The system seems stable but I get
the same error regarding iBCS.  Still working on the PPP problem too.
This may sound stupid but what is the iBCS module, where do I find it
and do I recompile it with 'make module' or make iBCS?

Thanks
george

If you wish to get and recompile ibcs (which lets you run binaries from
SunOS and a couple other Unix's) then ftp to tsx-11.mit.edu and get it from
I think the /pub/linux/ALPHA/ibcs2 directory.

Anyway, it allows Linux to run SCO UNIX binaries.

The module is available from
ftp://tsx-11.mit.edu/pub/linux/BETA/ibcs2
