	I'm running -current as of about 2 weeks ago & trying to build netbsd
	onto a 4/300 (using an ELC as a server). Its using the vanilla 'SUN4'
	kernel.

	Can boot it up ok, but when I tried newfs'ing the disk (a wren IV,
	two of whick work fine in the ELC) it blew up when I tried 
	'newfs sd0g' - every time (sd0a & sd0h are fine).

	It hands for a couple of seconds then:

CSR = 1118
panic: DMAWAIT1
syncing disks... data fault: pc=f8033050 addr=200024 ser=80<INVAL>
panic: kernel fault
Frame pointer is at 0xf80bb3f0
Call traceback:
	<I'll type it all in if needed :>
	

	On reboot it keeps panicing - it gets to the esp check & fails, and
	will keep on failing until I power off & back on.

esp0 at obio0 addr fa000000 pri 4: ESP100  <- note no newline, it 
					   hangs for about 3 secs & then
					   from CSR above

	a) Is this a known problem?
	b) Can I do anything to help track it down?
	c) Do I just go away & leave my 4/300 running sunos until the next
	   round of sparc changes come out? :)
