        FreeBSD 4.1-RELEASE i386 GENERIC
	Dell OptiPlex GX1
	SoundBlaster 16 ISA PnP

>Description:

	There are two problems with the AdvanSys SCSI ISA HBA
	probe:

	1. It cannot be disabled.  Disabling the device
	   driver in kernel configuration before booting
	   does not prevent the probe from executing.

	2. It thinks that the SoundBlaster 16 is a misconfigured
	   AdvanSys HBA. (Result: the probe fails).

	NOTE: This machine does not have an AdvanSys HBA.

	NOTE: On the same machine, 3.3-R GENERIC doesn't have
	either of these problems.  I don't know in what release
	the problems first appeared.

>How-To-Repeat:

	Boot the machine using the 4.1-R kernel and mfsroot
	floppies.  Go into full-screen kernel configuration.
	Disable all non-present devices, including AdvanSys.
	Save settings.  Exit kernel configuration and
	proceed with boot.  Observe console output.  The
	following will be seen:

adv1: Invalid baseport of 0x220 specified.  Nearest valid baseport
	is 0x320.  Failing probe.
unknown0: <Audio> at port 0x220-0x22f, [ ... ]
[ ... ]

	This is the first pair of adv1/unknown0 messages.
	There are a couple more, which I didn't write
	down.  All of the remaining adv1/unknown0 message pairs
	concern devices on the SoundBlaster 16.

>Fix:
	
	Unknown.
	NOTE: I don't have 4.1-R, just the boot floppies.
