Reason is suspend2. I have managed to get it working from console (suspend and 
resume) so now I am trying with X enabled. I have found references on several 
sites that it is possible if I disable the agpgart support in kernel (or make 
it a module and not load it). Here is some sources:

That did it. I found it in Processor Type and Features -> IOMMU support and 
disabled it. That also disabled agpgart. Thank you for your help.
