Indeed, and seeing that Nvidia only supports the "compute" mode of the 
driver on ppc64le, I'm having second thoughts about using them on my 
Talos II. I think I will revert back to AMD in this case and use plain 
the Titan cards on plain x86.

Partly yes, I could get CUDA working, on latest testing even, but it was 
very shakey and as soon as I tried to use both cards, it would crash the 
driver and I would have to reboot the system.

That made things a bit better, but still it's not entirely stable. It's 
not a tested/supported configuration and it shows.

Indeed, that is the case. Unless one owns a very high end data center 
card on ppc64le, it's probably not going to be supported by nvidia.

I'm not sure if I should ask you to close the bug as wontfix, I don't 
expect the situation will change soon, and it's not something that 
Debian can fix tbh. As I said I already considering using the cards on x86.

Nevertheless, I appreciate your help, thank you.
