Dual CPU doesn't load i686/64 bit Linux
 

System Specs:
Asus K8N DL
Nvidia 7300 GS PCI Express
2 GB ECC
Non-matching pair of Opteron 240

Linux:
Fedora Core 6 i586 works!
Fedora Core 6 i686 not working
Fedora 7 64 bit not working

Problem:

Either I get "Uncompressing Linux Kernel" and it just stays there forever, or I get "Brought up 2 CPUs" and it hangs there as well.

thank you

I have an Asus K8N DL with 2 Gig ram and dual Opteron 240 cpus. I don't have problems with i686 or 64bit distros (those I've tried). I have not tried Fedora. So, either you have a hardware problem, or a Fedora problem.

Try some liveCD's in i686 and 64bit to see if you have the same problem as with Fedora.

Note: with dual cpus, you need a SMP enabled kernel to be able to use both cpus. That may also apply to the 64 bit version (I'm not certain on that point).

Fedora is clean on my machine(see sig).

It works and doesn't work
 

I tried the system one CPU at a time to see if a CPU was defective. Finally, somehow, both CPUs are once more detected and this time the kernel passes the Brought up 2 CPUs and it work .

A new problem arises, the DVD boots up and then says that it doesn't detect it anymore by requiring a Fedora X DVD. On the verbose screen it says that it has CRC problems.

I will look into the boot up DVD problems, but thank you both for the suggestions and good news.

Is it possible that having non-matching CPUs can create problems?

thanks
