I am having problems with a NCR/Symbios 53c875 controller, configured as
ncr0 in my kernel.  This is on a 3.3-stable machine.  The problem occurs
when "large" amounts of data are being written, or deleted from either da0
or da1, my two scsi drives.  They are barracuda 4.5gig drives.  The system
goes into a userspace hang and the error respawns every 5 seconds or so on
ttyv0 and in /var/log/messages, here is the message...

/kernel: ncr0 queue is empty

It causes the system to become unusable, anyone with any idea how to fix
this please let me know.  

Thanks in advance
