Get page not present errors with a kernel compiled at this level - When using
nm to pop up the place where the crash occurs, it appears to be within brelse.
They will happen very quickly. Find enclosed the config file and the dmesg
output.

# Priapus - the watchdog
#
#
# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family. You must also specify
# at least one CPU (the one you intend to run on); deleting the
# specification for CPUs you don't need to use may make parts of the
# system run faster
#
machine "i386"
cpu "I486_CPU"
cpu "I586_CPU" # a/k/a Pentium(tm)
#
# This is the ``identification'' of the kernel. Usually this should
# be the same as the name of your kernel.
#
ident priapus
#
# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a complicated formula defined in param.c.
#
maxusers 20
#
# Space savers
#
#options "NMBCLUSTERS=128"
#options "BUFPAGES=128" # 512k for buffers
#
# A math emulator is mandatory if you wish to run on hardware which
# does not have a floating-point processor. Pick either the original,
# bogus (but freely-distributable) math emulator, or a much more
# fully-featured but GPL-licensed emulator taken from Linux.
#
#options MATH_EMULATE #Support for x87 emulation
#options GPL_MATH_EMULATE #Support for x87 emualtion via
#new math emulator
#
# This directive defines a number of things:
# - The compiled kernel is to be called `kernel'
# - The root filesystem might be on partition wd0a
# - The kernel can swap on wd0b and wd1b, defaulting to the former
# - Crash dumps will be written to wd0b, if possible
#
config kernel root on wd0 swap on wd0 and wd1 dumps on wd0
#####################################################################
# COMPATIBILITY OPTIONS
#
# Implement system calls compatible with 4.3BSD and older versions of
# FreeBSD.
#
options "COMPAT_43"
#
# Allow user-mode programs to manipulat their local descriptor tables.
# This option is required for the WINE Windows(tm) emulator, and is
# not used by anything else (that we know of).
#
options USER_LDT #allow user-level control of i386 ldt
#
# These three options provide support for System V Interface
# Definition-style interprocess communication, in the form of shared
# memory, semaphores, and message queues, respectively.
#
options SYSVSHM
options SYSVSEM
options SYSVMSG
#####################################################################
# DEBUGGING OPTIONS
#
# This line enables the kernel debugger, DDB, and the line following
# allocates extra space for a copy of the debugger symbol table which
# is stored in the initialized data area of the kernel. If you change
# the latter option, remove db_aout.o before compiling.
#
#options DODUMP #We dump core-image on panic
#options DDB #Kernel debugger
#options "SYMTAB_SPACE=113498" #This kernel needs LOTS of symtable
#
# KTRACE enables the system-call tracing facility ktrace(2).
#
options KTRACE #kernel tracing
#####################################################################
# NETWORKING OPTIONS
#
# Protocol families:
# Only the INET (Internet) family is officially supported in FreeBSD.
# Source code for the NS (Xerox Network Service), ISO (OSI), and
# CCITT (X.25) families is provided for amusement value, although we
# try to ensure that it actually compiles.
#
options INET #Internet communications protocols
#
# Network interfaces:
# The `loop' pseudo-device is mandatory when networking is enabled.
# The `ether' pseudo-device provides generic code to handle
# Ethernets; it is mandatory when a Ethernet device driver is
# configured.
# The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
# The `ppp' pseudo-device implements the Point-to-Point Protocol.
# The `bpfilter' pseudo-device enables the Berkeley Packet Filter. Be
# aware of the legal and administrative consequences of enabling this
# option. The number of devices determines the maximum number of
# simultaneous BPF clients programs runnable.
#
pseudo-device ether #Generic Ethernet
pseudo-device loop #Network loop back device
pseudo-device sl 2 #Serial Line IP
pseudo-device ppp 2 #Point-to-point protocol
pseudo-device bpfilter 4 #Berkeley packet filter
#
# Internet family options:
#
# TCP_COMPAT_42 causes the TCP code to emulate certain bugs present in
# 4.2BSD. This option should not be used unless you have a 4.2BSD
# machine and TCP connections fail.
#
# GATEWAY allows the machine to forward packets, and also configures
# larger static sizes of a number of system tables.
#
# MROUTING enables the kernel multicast packet forwarder, which works
# with mrouted(8).
#
# IPFIREWALL enables support for IP firewall construction, in
# conjunction with the `ipfw' program. IPFIREWALL_VERBOSE does
# the obvious thing.
#
# ARP_PROXYALL enables global proxy ARP. Beware! This can burn
# your house down! See netinet/if_ether.c for the gory details.
# (Eventually there will be a better management interface.)
#
options "TCP_COMPAT_42" #emulate 4.2BSD TCP bugs
options MROUTING # Multicast routing
# dropped packets
#####################################################################
# FILESYSTEM OPTIONS
#
# Only the root, /usr, and /tmp filesystems need be statically
# compiled; everything else will be automatically loaded at mount
# time. (Exception: the UFS family---FFS, MFS, and LFS---cannot
# currently be demand-loaded.) Some people still prefer to statically
# compile other filesystems as well.
#
# NB: The LFS, PORTAL, and UNION filesystems are known to be buggy,
# and WILL panic your system if you attempt to do anything with them.
# They are included here as an incentive for some enterprising soul to
# sit down and fix them.
#
# One of these is mandatory:
options FFS #Fast filesystem
options NFS #Network File System
# The rest are optional:
options "CD9660" #ISO 9660 filesystem
options FDESC #File descriptor filesystem
options KERNFS #Kernel filesystem
options MFS #Memory File System
options MSDOSFS #MS DOS File System
options NULLFS #NULL filesystem
options PROCFS #Process filesystem
options UNION #Union filesystem
#####################################################################

# IBCS2 (SCO Unix, ISC) SVR3.2 emulation stuff
# - Allow me to run SCO binaries!
#
options "COMPAT_IBCS2"
options "IBCS2"
#####################################################################
# SOUND DEVICE EXCLUSION
#
# Here we put exclude commands for the purpose of excluding device drivers
# for sound cards we do not have. This should hopefully
# result in a decreased text size of the kernel, leading to less paging
# on my memory challenged machine!
#
options EXCLUDE_GUS # NO GUS support
options EXCLUDE_GUS_IODETECT # NO GUS io detection
options EXCLUDE_GUSMAX
options "EXCLUDE_GUS16"
options "EXCLUDE_AD1848" # No Microsoft Sound System, GUS
options EXCLUDE_MSS # No Microsoft Sound System
options EXCLUDE_PSS # No Personal Sound System
options EXCLUDE_PAS # NO Pro Audio Studio support
options EXCLUDE_PRO_MIDI # NO PAS MIDI support
#####################################################################
# MISCELLANEOUS DEVICES AND OPTIONS
#
# Of these, only the `log' device is truly mandatory. The `pty'
# device usually turns out to be ``effectively mandatory'', as it is
# required for `telnetd', `rlogind', `screen', `emacs', and `xterm',
# among others.
#
pseudo-device pty 16 #Pseudo ttys
pseudo-device speaker #Play IBM BASIC-style noises out your speaker
pseudo-device log #Kernel syslog interface (/dev/klog)
#####################################################################
# HARDWARE DEVICE CONFIGURATION
# ISA and EISA devices:
# Currently there is no separate support for EISA. There should be.
# Micro Channel is not supported at all.
#
# Mandatory ISA devices: isa, sc, npx
#
controller isa0
#
# Options for `isa':
#
# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so
# that the PS/2 mouse driver doesn't conflict with the console driver.
#
# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so
# that multiple devices can share the same IRQ, provided that the
# hardware supports it (it usually doesn't).
#
# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
# than 16 megabytes of memory. It doesn't hurt on other machines.
# Some broken EISA and VLB hardware may need this, too.
options ALLOW_CONFLICT_IOADDR
options ALLOW_CONFLICT_IRQ
options BOUNCE_BUFFERS
device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr
#
# Options for `sc':
#
# NCONS specifies the number of virtual consoles. Specification of
# this value is mandatory. Due to a compiler bug, when compiling with
# GCC 2.6.0 this option must be a power of two.
#
# FAT_CURSOR specifies the use of a large block cursor rather than the
# hardware default underline.
#
# HARDFONTS allows the driver to load an ISO-8859-1 font to replace
# the default font in your display adapter's memory.
#
# UCONSOLE enables code to let any user get output intended for the
# console.
