Hi Adam and Kerry,
Does it have some relationship with PCI FMA support? Accordding to Adam's
description, PCI FMA may have interfered here.

Yes, I have tried both and both return 0xffffffff for all values.
I unloaded my driver and tried it as well. I got the same results.
I turned on my PCI Bus Analyzer and verified that the command was accessing my
device and that my device was not returning 0xffffffff, but instead valid data.
So I guess that proves that this problem doesn't involve my driver at all?
I am going to try some other things:
1. My company has several other PCIe devices that we make. I am going to add
a different device and try to read registers from it. If the other card works,
I think I can assume that the problem lies in some kind of incompatibility in
my device.
2. If I can't read from the different device. I am going to commandeer
another host machine and install OpenSolaris 2008.11 on it. And I will give it
another go. Maybe it's my box.
