>Release:        FreeBSD 2.0.5-RELEASE i386
>Environment:

	SA486P AIO-II with onboard NCR SCSI and IDE drive. Disk is SEAGATE ST31200N.
	Processor Intel 486DX2/66. I had to disable parity on PCI to work at all.
	This was true on previous FreeBSD versions, also (1.1.5 and 2.0).

>Description:
	I am trying to install FreeBSD 2.0.5-RELEASE on the said board.
	2.0 did run fine on this machine (SA486P AIO-II with onboard NCR SCSI).
	Now I am getting messages like this (extracted from dmesg):

	...
