>Description:
	It seems that the high-speed (38400 bps) silo overflows are back.
	They are occurring at regular intervals, usually 1 or 2 at a time,
	occasionally as high as 12:

     Sep  4 09:21:00 starwolf /netbsd: zstty0: 12 silo overflows, 0 ibuf floods

	This is during high activity on the machine.  Under 1.4, I had
	no such problems.
>How-To-Repeat:
	
	[sparcstation IPX]
	Connect via ppp at 38400 and start intense network activity out
	the ppp interface (ftp, sup, whatever).
