 	System      : OpenBSD 2.1
 	Architecture: OpenBSD.i386
 	Machine     : i386
 >Description:
 
 	Resolution of earlier reported problems.  Apparently running the
 	system under moderate load was overpowering the Adaptec 1522 SCSI
 	controller.  Upgrading to a 2940 made the lockups vanish.

 >Fix:
 	Don't install low-end consumer-grade hardware.
