Still is error in atlas package on 2 machines with athlon processors

[Zbigniew Komarnicki]

Hello!

I would like to ask you for help with this issue, because about 4 month ago I 
tried compile atlas (ports/math/atlas) and today and still with no success. I 
still obtain the following assertion error:

I have from dmesg the following processor:

On similar machine at my work I also obtained similar assertion error. 
Whats is going on here? Could you help me?

It nervous me that this is not working (4 months pass and still not compiling 
with success), but I don't know why? Maybe it is hardware error? or maybe 
someone has this same problem? Please for your help and suggestions how to 
solve this problem.

If you need more information I send it to you.

I'm sorry for my English.

Thank you in advance.
