Hi, 

I've been having the same problem for the past year but never really got 
the problem resolved, although I have been running 1.6.2 without any 
problems. The best I could find was the following bug report as reported 
by someone else on the mailing list: 
http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=25966

Apparently, this has nothing to do with scsi but something else entirely.  
I don't know if this issue has been fixed in the -CURRENT kernels since I
haven't had time to play around with my mac lately. I've tried the
"wdcdebug_mask" workaround but it hasn't worked for me. Your mileage may
vary though.

Hello.
I'm using Apple Powermac Beige G3 (PowerPC 750 -based system according to 
Open 
Firmware information) and I have a problem during NetBSD 2.0 boot. I've 
used 
a floppy-type installation. The problem appears when the kernel has been 
already loaded and started the hardware detection. It stops with strokes:
	...
	wsmux1: connecting to wsdisplay0
	md0: internal 2048KB image area
	scsibus0: waiting 2 seconds for devices to settle...

and after that the system hangs up.
I've try to remove ZIP-drive from the system, but it don't cause any 
effect.
My Open Firmware variables are:
auto-boot? 		false
output-device 		screen
input-device		kbd
real-base			F00000
load-base		600000
boot-device		fd:0
boot-file			netbsd
boot-command	begin ['] boot catch 1000 ms cr again

I've also tried to install the appropriate patches (such as 
SystemDisk-patch), 
but it didn't cause any effect too. Also I've tried to use UserConf, where 
I've manually disabled all scsi*-marked devices, but the situation hadn't 
change.

Could anyone tell me what have I done wrong or forgot?
ps. sorry for my language, haven't practice for a long time :)
