 I get the same trap on my firewall box (FreeBSD 4.1-release)  after the 
 3com driver has filled its buffers ("xl0: No memory for RX list -- 
 packet dropped" scrolling off the screen) and I try to do just about 
 anything... even halt.

 I have a similar problem on 4.7-STABLE and the Stack Trace seems to be 
 identical.
 I could reprodruce this every time.
 
 When I do a
 
 cp -R /mnt/FAT32 /mnt/nfs
 
 on a fat32 mounted partition and copy this over to the FreeBSD machine from
 Linux (FreeBSD is NFS Server/Linux is Client), FreeBSD crashes everytime 
 after ~5 Seconds.
 
 I tried to copy a bunch of data from OpenBSD to FreeBSD and the problem 
 did not occur, however I do also not have
 a Fat32 partiton mounted on OpenBSD, as it seems that when I copy data 
 over to FreeBSD from a native Linux partition
 also everything goes well.
 
 
 Here's my data:
 
 Linux Kernel 2.4.20
