>Description:
	My A3000 hangs when attaching to a HP Scanjet II cx.
	This happens right after the string "scan0: HP ScanJet IIcx" is
	printed to the console. The SCSI bus busy LED stays lighted.

	Yes, the SCSI bus was properly terminated. The same scanner works
	fine with NetBSD-1.2_BETA on a i486 machine it is normally connected
	to via an Adaptec 2940 interface.

	I booted into the debugger and tried to toggle several of the sbic.c
	switches (sbic_enable_reselect=0, sbic_no_dma=1,
	sbic_parallel_operations=0), without any change in behaviour.

	I guess I'm a victim of the remaining 1% of bugs in the Amiga sbic.c
	driver after the last big change just before -1.1.

	Note that there is another report (although not as a formal PR to us)
	from neil@crash.drempel.org.uk (Neil Brewitt). He tried to use a 
	MUSTEK 6000 with an A3000. His scenario is a bit different: The machine
	survives the auto-configure period, then any process trying to talk
	to the Mustek hangs in "disk wait" (D).

>How-To-Repeat:
	Connect HP Scanjet to built-in SCSI interface; reboot.
>Fix:
	Fix: not known.
	Workaround: switch scanner off before booting and don't use it.
