>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.

 I have the same problem with the same card. When I try to do a remote
 install via ftp the transfer speed is ridiculously low. ( 8Kbps on a 
 10Mbps ethernet).
 
 Please can someone fix this?

 No, I think it's not the same problem. You try to install 2.2.5, right?
 But in 2.2.6-BETA (or just before it) the lnc driver code was changed
 making it working though not quite :-(  In my case speed is lowered on
 heavy loaded net (many transferred data) not at once.

 I'd had a same problem on FreeBSD-3.2STABLE.
 
 PC is HITACHI's desktop PC, PC-5DC01-ZD0MA(FLORA330DC1)
 (see http://www.hitachi.co.jp/Prod/comp/OSD/pc/old/330_9704.htm#dc1,
 but in Japanese...), which has internal 10BASE-T ethernet, my dmesg is
    /kernel: lnc1: <PCNet/PCI Ethernet adapter> rev 0x16 int a irq 11 on
 pci0.5.0
    /kernel: lnc1: PCnet-PCI II address 00:00:1a:0d:e7:11
 
 And when sending/receiving big-sized file on http or ftp, appear
 following message,
    /kernel: lnc1: Framing error
    /kernel: lnc1: Receive CRC error
    /kernel: lnc1: Missed packet -- no receive buffer
 and thruput going worse, and it will recover when machine is rebooted.
 (I still haven't  test ifconfig down then up, sorry.)
 
 Does anyone already fix this problem, or patch(es) exist?
