Install failure SCSI

[LULANI Olsi <olulani@amc.al>]

I am using a Adaptec SCSI 7880 controller. My system has been using RedHat
7.2 but due to instability problems I decided to switch to OpenBSD. I was
using OpenBSD 3.2. The system boots from the CD, initialises the disks,
writes the disk labels without problems, initialises the partitions,
configures the network and than asks if I am ready to start the
installation. I answer yes and the system than starts to decompress and
install  the .tgz files. A few seconds later the kernel generates a couple
of SCSI errors, prints a series of numbers like 310, 311, 312 .. etc and
finally it syncs the discs and reboots the system. 
 
I repeated the installation and found the disk partitions to be existing on
disk but the SCSI errors again come up and the installation got interrupted
again.
 
Any clues about this situation or how to recover from it if possible. I do
not want to go back to RedHat.
 
     Sincerely
Mr. Olsi Lulani
