>Release:        FreeBSD 2.2.6-BETA i386
>Environment:

	Allied Telesyn AT-2450T (PCI) ethernet adapter card

>Description:

	After sending and receiving (simultaneously) about 80Mb of data
	or just sending (not receiving) about 150Mb the
		/kernel: lnc1: Framing error
		/kernel: lnc1: Missed packet -- no receive buffer
	messages begin to appear and the device perfomance significantly
	decreases. Only ifconfig down and then up lnc1 interface can help for
	some time.

>How-To-Repeat:

	Try to do ftp and send and receive a big amount of data.

>Fix:
	
	I don't know.
