Hi. Odd problem. I just installed 8.0 on a machine (kernel hacking test machine). I set about testing some old modules I had around, just to see that the build env. was in order and found the following discrepency: # insmod mod_hello.o mod_hello.o: kernel-module version mismatch mod_hello.o was compiled for kernel version 2.4.18-4GB while this kernel is version 2.4.18-64GB-SMP. $ uname -r 2.4.18-64GB-SMP $ less /lib/modules/`uname -r`/build/.kversion 2.4.18-4GB Ummmm. What could be behind this discrepency, and what would be the recommended fix? 1) Change the symlink at /lib/modules/2.4.18-64GB-SMP/build? 2) change .kversion (seems rather unlikely) 3) something I haven't thought of yet FWIW, the machine only has 512 RAM, so a 64GB enabled kernel is definitely overkill here :-) Thanks. Michael -- Michael Fischer Happiness is a config option. michael@visv.net Recompile and be happy.

You have one kernel-source.rpm but several possible kernels you can install. The source cannot possibly be configured for all versions at the same time.
1) Change the symlink at /lib/modules/2.4.18-64GB-SMP/build? 2) change .kversion (seems rather unlikely) 3) something I haven't thought of yet
4) cd /usr/src/linux && make mrproper && make cloneconfig && make dep After that you can compile modules against the running kernel.

Then install k_psmp. It's also the only way to run vmware on an smp machine if you want to use suse's precompiled kernel rpms regards Anders

Can you explain in just a little more detail what make mrproper and make cloneconfig does ?
make mrproper cleans up the kernel source tree and removes every old config. make cloneconfig is a SuSE hack to grab the config from the running kernel and configure the source to match. "make dep" finalizes the configuration so you can compile things against it. //Anders

That did it nicely. Thanks for the why and the how. Makes sense. Now I just can't figure out why printk()'s don't seem to show up anywhere... (not on /dev/console, /dev/ttyS0, /dev/tty0, /dev/tty1). hmmm. Michael -- Michael Fischer Happiness is a config option. michael@visv.net Recompile and be happy.
Is the box a Pentium4? If so, 8.0 detects an SMP and installs that kernel. Changing in YaST to the default is a breeze tho! Dylan On Monday 16 September 2002 19:44, Michael Fischer wrote:

Ummmm.
