I am running a machine built with a snapshot of current from 3/24/95.  If 
I aim tcpdump at a busy machine on on our ethernet I can produce a kernel 
panic fairly reliably.

the panic message;

Fatal trap 12	page fault while in kernel mode
fault virtual address 	= 0xf053bfe
fault code		= supervisor write, page not present
instruction pointer	= 0x8:0xf0187dbe
code segment		= base 0x0, limit 0xfffff,type 0x1b
			  DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL=0
current process		= Idle
interupt mask		= net

panic: page fault


The machine I'm running is a generic isa bus 486 with an smc nic
(WD8013EPC chipset).  A kernel sources diff between the 3/22 snapshot and 
what I'm running is at ftp://ftp.cas.usf.edu/diff/snap_diffs.  There 
appear to have been some vm changes in the 2 days between the snapshot and 
my grabbing the sources I am using.

thanx
