It sounds like your motherboard might need to be added to the drivers/pci/quirks.c with quirk_disable_all_msi ... can you try a different card with MSI just to see if it's something specific either to the fusion or the location in the system?

I don't have easy access to the hardware, it's just some lab machine I was told I could use for unrelated testing. Until this came up I'd never heard of "MSI", or "Fusion" before, and still don't have much idea about they are :-) Dave ^ permalink raw reply [flat|nested] 10+ messages in thread
