Hi Mr Reiter, Thank you for your answer. Actually yes, the same X310 runs perfectly in another machine. Its a i7 6th gen with ubuntu 18.04 kernel 4.15.0, libuhd and uhd-host on same version.
I think this can be some PCIe related setting on the BIOS, since the lspci shows [disabled] next to the base address, but I can't find any option to change it on the BIOS. Best Regards
