System: NetBSD 3.99.8 NetBSD 3.99.8 (PIP.MP) #1: Sun Sep 11 12:41:34 MEST 2005 i386
Architecture: i386
Machine: i386
	On i386 and amd64 MP plattforms silo overflows occur in not negligible
	amounts. Non MP kernels do not exhibit the problem. 3 com interfaces
	at baud rates of B50, B19200 and B4800 are affected.
	The systems should be fast enough the handle that load....
	Run 3 com interfaces on an MP kernel XP 2800+ or Athlon 64 X4 4400+.
