System: FreeBSD NightWish 4.3-STABLE FreeBSD 4.3-STABLE #1: Tue Jul 31 13:50:57 CEST 2001 tonyo@NightWish:/usr/src/sys/compile/NightWish i386

Network card: 3COM 3C905C-TXM EtherLink10/100PCI
Main board: Intel 82801BA (problem tested in another machine)
Processor: PIII/800
Kernel sources cvsupped from cvsup.hu.freebsd.org at 07/31/2001

>Description:

In this machine when we configure the xl0 device (3com Etherlink), the processor usage go up, the whole system extremly slow down. In other cases the systemi just hang up, and we can do only cold reboot.  

The card with other OSs (like linux) works fine. The problem only exists in FreeBSD.

>How-To-Repeat:
Just ifconfig the xl? interface with this card. 
>Fix:
no ideas.
