Let me know if there is a way and I'll capture one When the system panics it shows the following on the console: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x1c fault code = supervisor write, page not present instruction pointer = 0x20:0xc0447876 stack pointer = 0x28:0xc7db8960 frame pointer = 0x28:0xc7db8978 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 = 27 (swi1: net) trap number = 12 panic: page fault Uptime: 8h23m13s Cannot dump. No dump device defined. This machine is used as my firewall/router/bridge and some of the network interfaces are configured to use polling. I'm using pf for the firewall and if_bridge for bridging some of the interfaces together (it has 7 interfaces). >How-To-Repeat: Here's my kernel config: machine i386 cpu I586_CPU ident NET4801 makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols options SCHED_4BSD # 4BSD scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options INET6 # IPv6 communications protocols options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_ACL # Support for access control lists options UFS_DIRHASH # Improve performance on big directories options MD_ROOT # MD is a potential root device options NFSCLIENT # Network Filesystem Client options NFS_ROOT # NFS usable as /, requires NFSCLIENT #options MSDOSFS # MSDOS Filesystem #options CD9660 # ISO 9660 Filesystem options PROCFS # Process filesystem (requires PSEUDOFS) options PSEUDOFS # Pseudo-filesystem framework #options GEOM_GPT # GUID Partition Tables. options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options COMPAT_FREEBSD5 # Compatible with FreeBSD5 options KTRACE # ktrace(1) support options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options CPU_GEODE # Mandatory options CPU_SOEKRIS # Recommended options ADAPTIVE_GIANT # Giant mutex is adaptive. device apic # I/O APIC device isa device pci # Floating point support - do not disable. device npx # ATA (IDE) disk - required for CompactFlash too device ata device atadisk # ATA disk drives # Serial (COM) ports device sio # MII bus support is required for some PCI 10/100 ethernet NICs device miibus # MII bus support device sis # NS DP83815 Fast Ethernet device driver # Soekris vpn1211 #device hifn # Hifn 7951, 7781, etc. device random # Entropy device device loop # Loopback device ether # Ethernet device pty # Pseudo-TTY device md # Memory "disks" device gif # IPv6 and IPv4 tunneling device tun # Packet tunnel (required by PPP) device bpf # Berkeley packet filter device pf device pflog device pfsync device if_bridge # USB support device ohci # OHCI PCI->USB interface device usb # USB Bus (required) device ugen # Generic device uhid # "Human Interface Devices" device ukbd # Keyboard device ulpt # Printer device umass # Disks/Mass storage - Requires scbus and da # SCSI peripherals (required by USB) device scbus # SCSI bus (required) device da # Direct Access (disks) options ALTQ options ALTQ_CBQ options ALTQ_RED options ALTQ_RIO options ALTQ_HFSC options ALTQ_CDNR options ALTQ_PRIQ options DEVICE_POLLING options NSWAPDEV=0 >Fix: don't know >Release-Note: >Audit-Trail: >Unformatted:
