>Environment:

The problem occurs on a PC running FreeBSD 3.3 and acting as a NFS server
for my lab. It has 8 external scsi UW disks : 4 disks on a tekram 390 DF,
4 other on another tekram 390 df. It has also an adaptec 2940 for a DLT
tape streamer and a narrow scsi disk. 


Here's the uname -a output :

>Description:

After two months of perfect production, my NFS server running FreeBSD 3.2
started to crash unexpectedly. I changed the complete hardware of the CPU
(mainboard, memory, ethernet card (fxp0)) and it still crashed. I updated
to FreeBSD 3.3 (changing the system disk as well). It crashed several other 
times. I noticed at this time that it always paniced in ip_reass ou fxp 
driver. So I changed the fxp card for a brand new DIGITAL DE500, namely de 
driver. And it kept on crashing, with different place of crash in the code 
but still in the networking part of the kernel. Please find enclosed 2 
uuencoded traces from kgdb run on the 2 vmcore I managed to get yesterday 
and today.
