Dear Bjorn, maybe it helps to provide some more information. I can reproduce the same problem on 3 different mainboards from 2 different vendors: - Gigabyte AB350 Gaming CF - Gigabyte Z270X Ultra Gaming CF - MSI Z370 Tomahawk I now have all 3 systems ready at hands to run additional tests if needed. I have updated the information (lspci output, dmesg output) for all three boards here: https://owncloud.denx.de/index.php/s/wXiCMMYJodGj5Kr Thanks in advance!
