Hi all, I've run into an issue where ipxe.efi fails to detect/initialize any NICs when the uefi network stack is disabled. When the stack is enabled, everything works perfectly. However, as I understand it, iPXE does not require the UEFI stack as long as it has a driver for the NICs -- indeed on our non Apollo Lake systems with the same NICs (I210 8086:1533) the UEFI network stack does not need to be enabled for iPXE to detect and initialize the interface.
So far every Apollo Lake system we've tested (5 or so baseboards) exhibit this issue. Here's a paste <https://pastebin.com/mimn0s9E> of a log from a failing system, the failure being: EFIDRV PciRoot(0x0)/Pci(0x14,0x0)/Pci(0x0,0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) could not connect new drivers: Error 0x7f37e09a It appears to me like the uefi ConnectController boot service is what actually returns the error, but it I don't think that iPXE controls the internal behavior of that function; perhaps the root cause of failure is elsewhere? It could be that Apollo Lake simply implements some critical component in a different location, and we would merely need to point iPXE there in order to work around the issue -- but I don't understand the iPXE stack well enough to really speculate. Do you have any suggestions on how we could continue to debug, or how we could potentially work around this issue?
