Please report this failure to the PCI maintainer and include system > chipset information. The DL360 G3 is pretty ancient. The HP NC370F quickspecs (http://h18004.www1.hp.com/products/quickspecs/12196_na/12196_na.html) say it is supported on the DL360 G4, G4p, and G5, but not the G3. I have no idea why. I assume the NC370F has never been able to use MSI on this box with any kernel? We have quirks that disable MSI globally on some machines; maybe we need to do that on this system as well. Can you attach a complete dmesg log and output of "lspci -vv"?
