I have recently installed an SPARCstation SLC SunOS 4.1.1, replacing a 
SUN 3/50, using a CDC Wren IV disk.  We now see scsi error messages comming
from the esp0 scsi comtroller.

What is going on?  I am using a GENERIC kernal right now.  Should I 
configure a new kernal?  Is there something that I missed when installing
the asyncronous Wren IV onto the SLC.

Any and all help would be appreciated.  Below is a listing of the error
messages that I am getting.

Thanks in advance.
