@george1421 Hi George,
Yes it works with ipxe.efi but with a message which I do not have with realtek.efi, see screenshot:
https://drive.google.com/file/d/1eupCfc1Z5FROhi45pLlSWJsOk-AdtHt_/view?usp=sharing
The 2nd line on the screenshot starting with r8169 does not appear with realtek.efi
It is why I thought it was better to use realtek.efi
However it does not change anything when it comes to the kernel versions: same results as with realtek.efi, i.e. working up to 4.18.11, and not working after that.
NB: the first line with the error message starting with “db_root: cannot open: /etc/target” appears with both realtek.efi and ipxe.efi
Thanks
David.
