 I have a similar issue here using samba, nfs or ftp. With NFS it crashes 
 even faster than with samba but I use mainly samba.
 
 I was running 6.1-RELEASE. I cvsup'd to 6.2-BETA3 and applied a patch for 
 the em driver supplied by Jack Vogel. This fixed the same issue I was having 
 on the em card installed in the box.
 
 Under laod and with traffic the box would lock up requiring a hard reboot. 
 On the console there was an xl0:Watchdog Timeout error.
 
 It is a Tyan Thunder K7 motherboard with the latest BIOS. It has 2 onboard 
 3com NICs. It is SMP enabled with 2 AthlonMP CPUs. I am willing to give a 
 developer access t the box to troubleshoot.
