The symptoms I see on my ia64 box are that as soon as the driver tries to touch the Region 0 BAR via mmio, the system gives me a MCE. This is probably because the card fails to respond on this address and thus gives some type of PCI bus timeout. My suspicion is that the card requires some firmware setup that the on-board BIOS does before the BARs respond (and since this is an ia64 box, it doesn't run the BIOS). Could someone (i.e. Jeff) with access to the Docs have a look and see if this suspicion can be verified (or someone with a card try it in an ia64 to see if the same symptoms are observed)? Thanks, James
