I've just had a couple of hangs on my Ultra1 (the first time
	its misbehaved under 1.5X).

	Both times were while running the SunOS 4.x netscape binary, and
	both resulted in a complete hang short of L1+A

	The last dmesg entries were:

esp0: error:
csr=b2930a13<INT,ERR,DRAINING=0,IEN,ENDMA,DSBL_SCSI_DRN,BURST=0,TCI
esp0: DMA error; resetting
esp0: !TC on DATA XFER [intr 10, stat 87, step 4] prevphase 101, resid 1f0
esp0: waiting for SCSI Bus Reset to happen

	and trace reports (all via hamfisted c&p):

zsc_intr_hard()

	I'm running two wide SUN2.1G disks, and disk activity was light
	(I'v run both into the ground for sustained periods without incident
	otherwise).

	Does anyone have any thoughts on what might be up, or any additional
	information I could get which might help?
