SMP and 2nd cpu
 

Hay i've been trying to sort this for a while and have had no luck searching around so i hope some one here can shed some light on it

the machine is a dual 1200 amd athlone with a gig ram after re-compiling the 2.4.29 kernel for slackware 10.1, apon reboot i get kernel NULL pointer msg and the boot either fails or i loose network support.. below is a copy of the syslog

Thanks a ton if you can help out with this, i reckon it has somthing to do with NFS but im not to sure...

You will need to build a new kernel. First of all:
As it says, you need highmem support if you want to use all your RAM. Use the '1-4 GB' setting. As for the cause of your oops, I am not sure. What makes you think its NFS? According to your log it is happening during boot before NFS would ever be started...

In any event, I would compile a new kernel with highmem and see where that gets you. If you are still getting the oops after that then post much more detail on how/when it is happening.

kk thanks for that little bit, building a new one now. nice site btw

Ok i recompiled with the highmem still no joy same error as above the oops happends just after the system hits runlevel 3 and gose multi user and as the hotpluging kicks in

The above message may or may not be the cause of your problem but I have seen it before on machines I have worked on, the fix is usually to disable acpi by passing acpi=off to the kernel at boot time.
