Subject: kernel modules missing symbols and not loading
Message-ID: <3182823.r2jDsolsb3@thinkpad.nmecs.com>
Content-Type: text/plain; charset="us-ascii"

Hello Hello,

I have run into a problem that has stumped me. I downloaded the kernel source
for linux 3.3.4 and configured it the way I want it. I started by untarring
the linux-3.3.4.tar.bz2 file then running

make mrproper
make prepare
make menuconfig

After configuring I ran

cat .config > myConfig.3.3.4
make bzImage

After that finished I copied the kernel to my boot folder so I could boot it
after building the modules, then started over again and ran

make mrproper
make prepare

But this time I copied my config file to .config and ran

make modules

After a while it finished and I installed the modules via

make modules_install
depmod -a 3.3.4-mykernel

Everything worked correctly with no errors. I rebooted and the system gave me
constant errors saying xx kernel module could not be loaded because it was
missing symbols. When I configured the kernel I included all the options
necessary under Module versioning support, ie;

(Module versioning support)
MODVERSIONS=y
(source checksum for all modules)
MODULE_SRCVERSION_ALL=y

I assumed this was all I needed to make the modules work. Now I know you are
going to say why didn't I just compile the kernel and modules together?

I wanted to build the kernel and modules separately so I could have one kernel
optimized for my netbook and one for my Core2Duo without having to recompile
everything. I wanted to tar it all up and copy it over. But the kernels and
modules will not work together on either system. So what gives?

I googled around but only found old documents talking about this, is there
something new with 3.3.4? I have done this before with older kernels before
the 3 series, but I have not attempted since 3.x has come out.

I appreciate all your advice!

Matt,
thanks for suggesting smartctl. Ubuntu had loaded a GUI version. It looks
fine on all drives but the smallest (and therefore probably oldest) one. I
had to apt-get install smartmontools to get the command line version. The
GUI was returning almost immediately from the self test with no values for
any test parameters. The command line gave the data below. The error count
kept increasing when I re-ran it. It looks like the drive is trying to
start up and finding a smart mode error. If I just mount the volume (VFAT),
it does not make the sound and the directory appears to work correctly
(virtually nothing left on that drive, anyway). But when I unmount it, and
try to run tests, it starts making the sounds again every minute or so, and
the error count begins to go up again. I guess it is time to shred the
drive. remove it and throw it away.

"Pre-fail" is the name (or description) of that particular SMART
counter, as is "Old Age". If there were positive and increasing values
in those rows, it could indicate a pre-failure condition. A brand new
drive still has prefail and old-age counters, even though it may not
fail or be old for years to come.

This just looks like you have an older drive where the counters are no
longer within acceptable range.

Do you have power management on this drive?

This could also cause that ABRT error.

The gist is that the read/write head on these drives parks itself too
often. While this does result in power savings while parked, the
drives are only designed to support 300k parks (consumer drives) or
600k parks (enterprise/RE2 edition).

Either way, the smart data will show how many times the head has been
parked via the "Load_Cycle_Count" parameter.

An (edited) example:

smartctl -a /dev/sda
Power_On_Hours 3377
Load_Cycle_Count 97972

The "solution" so far has been to use the "wdidle3.exe" DOS utility
provided by Western Digital to change the head-park idle timer to a
different value (or disable it all together).

Hi

I have a small Dell box that I have been using off and on for misc work
related sw testing (started with v 9.x Desktop).

I need to ramp up my personal training (as I am looking for work at the
moment) and have a question for the group.

Currently I am running 12.04 Desktop version with Apache, MySQL,
OpenSSh and some other server packages installed. I will be installing
Oracle next week for my next training project. However after the 12.04
upgrade I find that I can not access the Desktop Ubuntu machine from
anything on the local network. I can access apache, mysql locally. A local
ssh connections works just fine. Just can't do any of them from outside the
box from anything on my home/local network. I don't think there are any
running firewalls, so I am discounting that as an issue.

Would a fresh install of the Server version be a better long term solution
for working with those type of packages, or should I stick with my 4x
upgraded Desktop version?

and

Does anyone have any suggestions as to what I can look into to resolve my
network connection issue ?

Thanks
Joe Gibbs

You have multiple issues:

1) Existing User Space - You really already have this with the Desktop
applications and a hardened kernel:

https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule

2) Problems with Ubuntu 12.04 upgrade

See this post:
http://askubuntu.com/questions/126573/ethernet-connectivity-problems-after-upgrading-to-ubuntu-12-04lts

3) Need for Oracle

Please follow the instructions here to setup Oracle on 12.04
(everything should be the same): for 11gR2:

What's the difference between desktop and server?

The first difference is in the CD contents. The "Server" CD avoids
including what Ubuntu considers desktop packages (packages like X,
Gnome or KDE), but does include server related packages (Apache2,
Bind9 and so on). Using a Desktop CD with a minimal installation and
installing, for example, apache2 from the network, one can obtain the
exact same result that can be obtained by inserting the Server CD and
installing apache2 from the CD-ROM.

The Ubuntu Server Edition installation process is slightly
different from the Desktop Edition. Since by default Ubuntu Server
doesn't have a GUI, the process is menu driven, very similar to the
Alternate CD installation process.

Ubuntu server installs a server-optimized kernel (tcp/ip settings
and hardened kernel) by default.

Ubuntu Desktop will receive 3 years of support, while Ubuntu
Server will be supported for 5 years.

Is this a public facing machine?

It would probably be best to stay with your Desktop and just harden
the /etc/sysctl.conf switches, turn off all non-essential services
(bluetooth) and provide internal TRUST ip firewalling (if necessary).

Cannot answer the question, but I can tell you where to look to see why
the system is no longer on the network.

On the box which is no longer seen by the rest of your network:

First, check to see that the Ethernet device you are connecting to the
network is up and configured. Use ifconfig for that.

Next, make sure the routing tables are correct. Use route for that.

Next, make sure you can get outside. Easiest way is to go to a remote
web page.

Next, instead of using 'localhost' as the name for the machine, try
using its externally-visible IP address. E.G. if it is 10.5.1.2 then
use 10.5.1.2 instead of localhost for one of your 'inside the box'
tests.

All that will verify that the box is on your network and listening to
the external IP address to serve requests.

Now, from a remote machine, try to ping that machine. If it answers,
then you can reach it and things should have been working. Note also
that pinging or tracerouting with a port number can reveal listening
issues as well.

If you know when the change from working to not working happened, do a
find from /etc for any files which have changed since that 'known time'
(e.g. find /etc -newer <file with older-than date>)

Of course, this is all generic stuff, Lisa just said something very
ubuntu-specific. See her info first, but for everyone else the above
might help in time of need J
