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.

yes, i knew that.

one patch in my for-pci-next should address that.
