System: NetBSD white-dwarf 1.2.1 NetBSD 1.2.1 (GNOME) #1: Thu Aug 28 00:48:16 EDT 1997 root@white-dwarf:/usr/src/sys/arch/mac68k/compile/GNOME mac68k


>Description:
Kernels later than GENERICSBC-26 have been shown to hang with the line "sbc0 at obio0 : options=1<PDMA>" when booting on the above mentioned machines. This includes kernels GENERICSBC-27 thru GENERICSBC-36 and possibly including GENERICSBC-37.
	
>How-To-Repeat:
Try to boot any of these -current kernels on an LCIII or like system.
	
>Fix:
The only known fix at this time is to use a previous kernel that is known to work (GENERICSBC-26) or any others that have been found to work. (ADBTEST-160, possibly others)
