Thanks for you quick reply Jason.

I'm in a position where I run the 1.5V kernel and I can't really change
over night, so i tried to modify the driver to work with 1.5V ..

And it works quite well, I get the box up a little bit on the way ...

This is without any PHY's configured in the kernel ... if I configure ukphy,
it will detect it, and then hang at

'nfs_boot: trying BOOTP'

I'we tried booting without PHY's a couple of times, and it always ends up in
'device timeout' ...

Any ideas?
