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 Joseph Orthoefer
