The documentation states:

  "The disadvantage is, that this approach does not support realtime
   extensions like RTAI, because the Linux network stack is addressed."

How is "realtime extensions like RTAI" to be interpreted in the above?
Specifically, what is the position on using ec_generic with RT_PREEMPT?

It seems to work, but I am about to investigate a kernel hang when doing
reg_read with ec_generic.  I am suspecting that this might be related to
using RT_PREEMPT, in which case I really hope there is a reasonable
chance of fixing it.
