The "DMA channel not running" is completely harmless. It simply means
that the DMA channel is started after the new traffic has been inserted
in the DMA list. (The reason the DMA channel stopped in the first place
was that there was no more traffic.)
Does it make any difference if you disable the USB port that is used for
the second Ethernet interface (port 1, if memory serves me correctly)?
(You'll find it under "Drivers for ETRAX 100LX built-in interfaces".)
