OK.
I just tried this setup on my Kilauea board. Without any problems:

The PCIe device used here is the Intel PRO/1000 PT Desktop card.
Which Kilauea board revision are you using? And do you see the same problems with other PCIe cards as well?
I use Kilauea revision 1.2 and exactly the same network card as you. The problem is still here. It doesn't happen with other PCI-E card I have (10G Ethernet adapter).
I have a feeling that 2 Kilauea boards of the same revision may sometimes exhibit different behavior with the same version of u-boot. For example, with u-boot 2008.10-rc2 that comes with AMCC CD, memory was properly detected on one board in bootstrap option B but not detected on the another. I had to recompile u-boot and disable autocalibration to make things work on this board.
