System: NetBSD pip.kardel.name 3.99.8 NetBSD 3.99.8 (PIP.MP) #1: Sun Sep 11 12:41:34 MEST 2005 kardel@pip.kardel.name:/fs/IC35L180AVV207-1-n/IC35L120AVV207-0-e/src/NetBSD/netbsd/sys/arch/i386/compile/obj.i386/PIP.MP i386
Architecture: i386
Machine: i386
>Description:
	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....
>How-To-Repeat:
	Run 3 com interfaces on an MP kernel XP 2800+ or Athlon 64 X4 4400+.

>Fix:
	?
