DMA with current 2.4.x kernels

Usually one or the other, not both simultanously.  I use the tulip on 
almost all my systems.  One board produces "system error occurred" 
kernel messages, so I use the NE2k on that one.  And on my gateway 
machine I use both the Tulip and NE2k ports simultanously.

All the systems except the gateway are headless, no video, mouse, 
keyboard are connected... and no sound is used.  So the ISA bus troubles 
don't really affect me.

Ah the esoteric filesystems :)  Also something to check is if your HDD 
supports DMA.  Most do, but some of the older ones don't...  is it the 
original HDD or an aftermarket one?

One of these day's I'll do a more recent 2.4.xx patch for netwinder ;)
