Something that ocurred to me is that u-boot is initializing the PCI, and
the PCI networkd cards. Ideally this should not affect anything, but
can this be related to the issue?

It works fine with v4.10, but I have a similar problem on v4.11
(a351e9b9fc24e982ec2f0e76379a49826036da12), but it is not the same.
Similar as that system freezes on PCI initialization:

It freezes here...

But is different as this patch makes the the system to boot:
