No problem.
I am using a pci cmi 8738 in the first slot and it works with no lockups under AmigaOS 4.1.
But it locks up with full screen video under Linux so I use HDMI audio .

thanks for the link! i couldn't remember the details on this. hopefully aaron (at AOTL) can get those cards replaced in his future builds.
