PS: Unfortunately, N900 will not boot using nfsroot in 3.16+ at least,
and boot from MMC card is broken and has been for quite some time.

USB networking works fine with 3.19-rc3 and also MMC card rootfs.

Does nfsroot work for you? USB networking works as a module but not
build-in. [Patch is available for this one.]

u-SD card seems to have similar problem. If I try it after boot, I can
access it ok, but using u-SD card for rootfs fails. If it works for
you, it would be interesting to know.

I haven't tried nfsroot, but I've been using USB networking for ssh
for a couple of years without issues. I have g_ether as module.

Also I recently switched rootfs to u-SD card, and it (MMC) works fine
as builtin.

But I'm mounting it from userspace (using builtin initramfs inside
zImage), with a poll loop that waits for a device to appear. Maybe if you
do it from kernel you need to use root wait/delay etc. options?

Yes, it works if I mount it later. It fails when done directly using
root=, even with rootwait etc. Hard to believe, yes, but try it. You
can watch the results on console.
