MSI-X vector allocation failure in upstream kernel

2010-10-05 Thread Anirban Chakraborty
Hi All, I am trying to test qlcnic driver (for 10Gb QLogic network adapter) on a Power 6 system (IBM P 520, System type 8203) with upstream kernel and I do see that the kernel is not able to allocate any MSI-X vectors. The driver requests for 4 vectors in pci_enable_msix, which returns 2. The
