Some time after Dec 4 I started geting page fauls when installing a new
system to my laptop via the lp interface. It usually makes it through
include but not always. The last one failed the AM with src-2.2.0548
patches. This is the screen:
fault trap 12: page fault while in kernel mode
fault virtual address = 0x10
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf012c325
stack pointer = 0x10:0xf0197c50
frame pointer = 0x10:0xf0197c60
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
interrupt mask = net tty bio
panic: page fault

# This file, if present, will be read by make (see
/usr/share/mk/sys.mk).
# It allows you to override macro definitions to make without changing
# your source tree, or anything the source tree installs.
#
# This file must be in valid Makefile syntax.
#
# You have to find the things you can put here in the Makefiles and
# documentation of the source tree.
#
# One, and probably the most common, use could be:
#
CFLAGS= -O2 -m486 -pipe
#
# Another useful entry is
#
NOPROFILE= true
# Avoid compiling profiled libraries
#
# To have 'obj' symlinks created in your source directory
# (they aren't needed/necessary)
#OBJLINK= yes
#
# To compile just the kernel with special optimisations, you should use
# this instead of CFLAGS (which is not applicable to kernel builds
anyway):
#
COPTFLAGS= -O2 -pipe
#
# To compile and install the 4.4 lite libm instead of the default use:
#
#WANT_CSRG_LIBM= yes
#
# If you do not want unformatted manual pages to be compressed
# when they are installed:

#
#
# If you want the "compat" shared libraries installed as part of your
normal
# builds, uncomment these:
#
#COMPAT1X= yes
#COMPAT20= yes
#COMPAT21= yes
#
#
# If you do not want additional documentation (some of which are
# a few hundred KB's) for ports to be installed:
#
#NOPORTDOCS= true
#
#
# Default format for system documentation, depends on your printer.
# Set this to "ascii" for simple printers or screen
#
#PRINTER= ps
#
#
# How long to wait for a console keypress before booting the default
kernel.
# This value is approximately in milliseconds. Keypresses are accepted
by the
# BIOS before booting from disk, making it possible to give custom boot
# parameters even when this is set to 0.

#BOOTWAIT=0

#
# By default, the system will always use the keyboard/video card as
system
# console. However, the boot blocks may be configured to use a serial
port
# or probe the hardware to determine if the serial port or kbd/video
should
# be used.
#
# By default we use COM1 as our serial console port *if* we're going to
use
# a serial port as our console at all. (0x3E8 = COM2)
#
#BOOT_COMCONSOLE_PORT= 0x3F8
#
# Uncomment the following line to test if a keyboard is present. If the
# keyboard isn't there, use the serial port as console.

console.
#
#BOOT_FORCE_COMCONSOLE= true

earlier.
# If you have a XFree86 from before 3.0 that has the X distribution in
# /usr/X386, you want to uncomment this.
#
#X11BASE= /usr/X386

#
# If you have Motif on your system, uncomment this.
#
#HAVE_MOTIF= yes
#
# If the default location of the Motif library (specified below) is NOT

value.

a
# hint for various make-spawned utilities that they should use passive
FTP.
#
#FTP_PASSIVE_MODE= YES
#
# If you're resident in the USA, this will help various ports to
determine
# whether or not they should attempt to comply with the various U.S.

#
# Port master sites.

# remove the "/${DIST_SUBDIR}/" part.)
#
#MASTER_SITE_BACKUP?= \
# ftp://ftp.freebsd.org/pub/FreeBSD/distfiles/${DIST_SUBDIR}/
#
# If you want your port fetches to check the above site first (before

# you want.
#
#MASTER_SITE_OVERRIDE?= ${MASTER_SITE_BACKUP}
#
# Some ports use a special variable to point to a collection of

--------------------
What is my next step? Do I enable KTRACE? And what else? I am
reasonably skilled with the system, but not very knowledgable about
working with the kernel. I can use gdb. All guidance apperciated.
Thanks
