Hi,
I just put a netgear GA620 gigabit ethernet adapter in my DS20 (running a fresh
-current), and at boot it's probed as:
ti0 at pci0 dev 8 function 0: can't map memory space

I tried 2 different PCI slot (didn't try the 4 others :)
Any idea of how to solve this ? This box isn't in production yet, I can
experiment. The same board works fine in a PC with kernel build from same
sources works fine, but I got this board for the alpha ...

dmesg included below.
