Hi Marc,
it looks that the PCI enumeration of the LAN chip works fine, but then the register access fails. So lspci -vvnn lists the Realtec LAN [10ec/8168] correct, but network test fails to access the register. It's not possible to read out the MAC address. 0xFF on all places will be returned. I have attached the coreboot log file. On line 375 PCI: 01:00.0 [10ec/8168] enabled shows the bus. On line 994 down I can see assertion fails on AmdInitLate process. What does this mean? Can you help?
Thanks
Wolfgang
