Well, I decided to brow-beat this a little more.  My 4/260 is the 
fileserver for my MVME-147, and having build /usr/src/lib on it 
yesterday, I decided to install it ...

Immediately, I started getting the following on transfers of large files:

ie0: DMA underrun

Lots of 'em.  It doesn't seem to have trashed anything, that is after the 
new libc.so.12.3 was installed things kept working.  But, they are 
somewhat annoying, and could potentially lead to some trashed data, I'm 
sure.

Worth noting, I did get this message before when using the old "si" 
driver, but they're happening with much greater frequency.

I'll poke around and see what I can see, but if anyone else has any 
suggestions, I'm certainly willing to hear them :-)
