The panic message was saying something about "natd" being the active task. After having read about kernel panics with early 4.7-STABLE here I decided to cvsup and update. That didn't help too much, after a few hours (maybe 18 hours or so) I had the same crash again: FreeBSD gruft.de 4.7-STABLE FreeBSD 4.7-STABLE #22: Sun Oct 27 13:46:56 \ CET 2002 root@gruft.de:/usr/obj/usr/src/sys/EXPRESS i386 (cvsup was just before building the world and kernel from cvsup2.de.freebsd.org) Fatal trap 12: page fault while in kernel mode fault virtual address = 0xe0268800 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0194f50 stack pointer = 0x10:0xd902be48 frame pointer = 0x10:0xd902be6c 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 = 98 (natd) interrupt mask = net trap number = 12 panic: page fault The machine at the time of the crash usually has not a big load. There's no such process as setiathome or so running, which could overheat the CPU, the CPU temperature as shown in the BIOS is OK. The machine has three Intel fxp network cards, natd is running for to of the networks, both of which had just active component with DHCP and MRTG traffic every few minutes. My fw rules read like this in the beginning: --- CUT HERE --- add allow all from 192.168.1.0/24 to 192.168.1.0/24 # add divert natd all from any to any add fwd 192.168.1.1,3128 tcp from 192.168.1.0/24 to any 80 add fwd 10.0.1.1,3128 tcp from 10.0.1.0/24 to any 80 # add allow tcp from 127.0.0.0/8 to 127.0.0.0/8 via lo0 add deny tcp from any to 127.0.0.0/8 --- CUT HERE --- The same setup before the update to 4.7 ran without problems over months, the only change in the hardware last time was an addtional harddisk (all IDE). When booting I see one warning, I don't know exactly what to do about it: CPU: AMD Athlon(TM) XP1500+ (1343.06-MHz 686-class CPU) Origin = "AuthenticAMD" Id = 0x662 Stepping = 2 Features=0x383f9ff AMD Features=0xc0480000<,AMIE,DSP,3DNow!> real memory = 536788992 (524208K bytes) avail memory = 518770688 (506612K bytes) pnpbios: Bad PnP BIOS data checksum ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ has someone else similar problems or just an idea where to start looking?
