this helps a little bit with two effects.
Copying source-tree with scp(1):
Now I can see transfers with up to approx. 500kB/s - inaccurate
measured with scp(1),
but relation counts.
Transfer stalles after different data volumes with DMA-error on tty0,
but networking
port is not turned off. This happens after 30-80MB data transfers.
You can restart the whole copy at once again.

Copying source-tree with nc(1) tar-gzipped:
Transfer stops and starts with DMA-error every approx. 7MB with turning off NIC.

Yes, definately. See above.

Ethernet controller is turned on in BIOS, but booting via ROM is turned off.
Maybe did I not compile WOL to my (nearly) monolithic kernel? And if
so, I do not know the switch.

Is there a relation to DMA-error?

best regards.
