ipxe failes to boot in efi mode due to incomplete ipxe script

[Michal Kielkowski]

Out of the box booting using ipxe ends with kernel panic (see screenshot). It can be worked around by putting

initrd=boot-initrd

to command line option. However I think this should be addressed in the ipxe script template.

Please see
https://forum.ipxe.org/printthread.php?tid=10770
for reference.

Steps to reproduce:

1. Create Hyper-V machine, version 2 (efi). Optional: verify that regular PXE boot works.
2. Mount dvd image from https://boot.ipxe.org/ipxe.iso and set it as a boot defice
3. Commisioning ends with kernel panic.

Default script that does not work:
root@maas:~# curl http://10.0.0.1:5248/ipxe.cfg-00:15:5d:38:01:0f
#!ipxe
kernel http://10.0.0.1:5248/images/ubuntu/amd64/generic/focal/stable/boot-kernel

initrd http://10.0.0.1:5248/images/ubuntu/amd64/generic/focal/stable/boot-initrd
boot
root@maas:~#

What works:

root@laptop:~# cat /var/log/kern.log |grep Command

Hi, just wanted to add that we encounter the same issue on some of our machines. What all machines have in common is that they use an external 10GiB NIC (Aquantia) with EFI boot. Both HTTP and PXE options are failing, for PXE we receive the same output as in the image attached.

Is there a way for a manual fix? Which files do I need to edit in order to add the missing parameter (AMD64 machines)?
We are using DEB version of MAAS, so I guess the path should be "/lib/python3/dist-packages/provisioningserver/..." or simliar.

Best regars,
