aic7880 problem talking to CD-R

[Smith, Jeremy]

I had the same message with my UW when I moved from BIOS 1.25 to 1.32S4.
To correct the problem I strictly defined each of my SCSI devices in the
SCSI BIOS so that the UW would only attempt to negotiate things that the
devices were capable of doing. I found the biggest culprit was indeed
the wide neg. and that I had the problem with more than one device. You
should try making sure that you aren't letting the SCSI Host Adapter
request a configuration that the devices aren't capable of handling.

		My apologies; I apparently did not wait long enough for
something
	to happen while I was getting the "Unexepected busfree" errors.
	Eventually (it took something like 10 minutes) it will start
scrolling
	these messages very quickly:

	(scsi0:-1:-1:-1) Bad scbptr 16 during SELTO.
	(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
		SCSISEQ = 0x5a SEQADDR = 0x8 SSTAT0 = 0x10 SSTAT1 = 0x8a

		It seems to echo that forever, but I'll continue to keep
an eye on
	it and see if anything changes.
