Yes, the fstab-setup is important=E2=80=A6... but then I realized =
Matthew`s boot environment :
He has u-boot sitting on the pxe-Server, whereas the eeprom was flashed =
for completely diskless netboot=20
as a requirement .
With that setup in fact we will end up in n infinite loop of an 'genet0: =
gen_intr2=E2=80=98 -console-output,
regardless of fstab or whatever configuration elsewhere I tried.=20

I have now refreshed the eeprom to it=E2=80=99s default(where diskless =
pxe-boot is disabled )
And again successfully net-booted (14_current in this case) :

https://dmesgd.nycbug.org/index.cgi?do=3Dview&id=3D5917

Since netboot from u-boot on the uSD requiresdonly 1 command by hand =
(load net0:/boot/kernel/kernel
)(+ command :=E2=80=99boot=E2=80=99) and there=E2=80=99s no problem with =
the genet-driver I guess that=20
It=E2=80=99s an issue of the pxe-flashed eeprom where we don=E2=80=99t =
yet know exactly what happens.


So for now I guess netboot from uSD is a painless and well working =
setup,
while to be honest:
I don=E2=80=99t remember exactly at the moment how I figured to get it =
to work after trials&errors  :-) Ha Ha=20
But I=E2=80=99ll leave the uSD untouched or copy the folder to have a =
point for a tutorial or so if someone is interested in.
