Re: [coreboot] BDX-DE PCI init fail

Hi Hilbert. It might be nothing but if I have a look at your last attached log I can't see SeaBIOS finding any USB devices. There is just one Error mentioned: >ehci_wait_td error - status=80e42 So what is special with SeaBIOS and Broadwell-DE: you have to unset the config switch called
