Known bugs:

- ESIX 4.0.3A will not correctly create sockets, pipes, character
  devices or block devices on a remote NFS filesystem.

  LINUX does not have this problem.  Several bugs in the code were
  fixed to get these file types working.

- ESIX 4.0.3A has problems with NFS loopback when too many biod
  daemons are running.  I had to cut back to 2 biod daemons to get
  loopback NFS working reliably.  More than that causes exponential
  backoff behavior for some reason.

- ESIX 4.0.3A has a bug in the DMA code invoked by the SCSI
  passthrough interface that causes panics.  The problem has to do
  with trying to do DMA using buffers beyond the DMA-able boundary.
  To fix this, I added the following to /etc/conf/cf.d/stune and
  rebuilt the kernel:

  * DMA fix for SCSI pass-through
  MAXDMAPAGE	0

  This will not work on all machines; it works on mine because my
  machine has DMA hardware that can address all RAM.  However, I found
  that this fix prevents the floppies from working properly, so I am
  still looking for a complete solution.

- The queueing between the NFS server and the tape drive access daemon
  needs some work, it does not appear to be all that efficient.
