restate

Here's a mild addition to my last message.

I have DMA working in user space with the ni_pcidio driver. I want to move
this code to a realtime (RTLinux) version. Right now I'm noticing that 
the result from mite_bytes_transferred() is always 0 under RTLinux, which 
it obviously shouldn't be -- it should be nicely increasing during 
acquisition, which occurs in my user space code. 

I'm using comedi commands for acquisition and now suspect that the 
problem may lie in kcomedilib's implementation of comedi_command() vs.
comedilib's implementation.

Does anyone have DMA working with this driver in a realtime setting?
