iov bar is not assigned by BIOS, and kernel can not find range for it too. Lukas, can you post whole boot log with PCI_DEBUG enabled? That will tell exact why kernel does not assign them. Recent kernel from 3.4... should enable realloc when SRIOV bar is not assigned.
sorry for confusing, PCI_DEBUG does not break mlx driver, it is reallocation code that results: [ 3.555008] mlx4_core 0000:02:00.0: Missing UAR, aborting. -- Lukáš Hejtmánek
