>Release:        NetBSD-current kernel Jan 9  12:15:11 MET 1995
>Environment:
	
System: IPC NetBSD-current sparc something-or-other
Architecture: sun4c (IPC), Wren6 (scsi1), Wren8 (scsi2), 204mb (scsi2).

>Description:
	
	"panic: DMAWAIT1", and thrown into debugger.
	Is anything necessary?  Is it known?  Is it already fixed?
	NOTE: I can use the debugger (don't know what to do, though), but I
	only get about 53 characters across by 21 lines.  The real crash
	messages (later) are not readable.

>How-To-Repeat:
	
	Boot off Wren 6, SCSI1  (boot disk3 netbsd).
	Access SCSI2 disk in one of the following manners: (note: memory)
		a) df /dev/sd1c
		b) mount /dev/sd1c /mnt
		c) fsck /dev/sd1c
	Happened with previous kernels also, only I didn't have debugger in.
