Some months ago one of mine 411ARs lost all PCI info: built in card & any other PCI card I plug at the empty bay. It was in production for 6 months then, a XR9 using the mini-pci slot and the built in card as an 2.4GHz AP. Suddenly stopped working.
But still acessible via ether or serial console, accepting commands & config.
I gave up of this board, left it around. Installed V 4.5 at this time.
Now reading the forum I decided to power it up again - and - PCI functions are back. For how long, I don't know. I'm afraid to put it back in service.
