#
# Certain applications can grow to be larger than the 128M limit
# that FreeBSD initially imposes. Below are some options to
# allow that limit to grow to 256MB, and can be increased further
# with changing the parameters. MAXDSIZ is the maximum that the
# limit can be set to, and the DFLDSIZ is the default value for
# the limit. You might want to set the default lower than the
# max, and explicitly set the maximum with a shell command for processes
# that regularly exceed the limit like INND.

#####################################################################
# SMP OPTIONS:
#
# SMP enables building of a Symmetric MultiProcessor Kernel.
# APIC_IO enables the use of the IO APIC for Symmetric I/O.
# NCPU sets the number of CPUs, defaults to 2.
# NBUS sets the number of busses, defaults to 4.
# NAPIC sets the number of IO APICs on the motherboard, defaults to 1.
# NINTR sets the total number of INTs provided by the motherboard.
#
# Notes:
#
# An SMP kernel will ONLY run on an Intel MP spec. qualified motherboard.
#
# Be sure to disable 'cpu "I386_CPU"' && 'cpu "I486_CPU"' for SMP kernels.
#
# Check the 'Rogue SMP hardware' section to see if additional options
# are required by your hardware.
#
# Mandatory:
options SMP # Symmetric MultiProcessor Kernel
options APIC_IO # Symmetric (APIC) I/O
#####################################################################
# CPU OPTIONS
#
# You must 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. This is especially true removing
# I386_CPU.
#
cpu I686_CPU # aka Pentium Pro(tm)
#####################################################################
# COMPATIBILITY OPTIONS
#
# Implement system calls compatible with 4.3BSD and older versions of
# FreeBSD. You probably do NOT want to remove this as much current code
# still relies on the 4.3 emulation.
#
options COMPAT_43
#
# Allow user-mode programs to manipulate 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
#
# KTRACE enables the system-call tracing facility ktrace(2).
#
options KTRACE #kernel tracing
#
# PERFMON causes the driver for Pentium/Pentium Pro performance counters
# to be compiled. See perfmon(4) for more information.
#
options PERFMON
# XXX - this doesn't belong here.
# Allow ordinary users to take the console - this is useful for X.
options UCONSOLE
# XXX - this doesn't belong here either
options USERCONFIG #boot -c editor
options VISUAL_USERCONFIG #visual boot -c editor
# XXX - neither does this
options ROOTDEVNAME=\"da0s1a\"

# NETWORKING OPTIONS
#
# Protocol families:
# Only the INET (Internet) family is officially supported in FreeBSD.
# Source code for the NS (Xerox Network Service) is provided for amusement
# value.
#
options INET #Internet communications protocols
options INET6 #IPv6 communications protocols
options IPSEC #IP security
options IPSEC_ESP #IP security (crypto; define w/ IPSEC)
# netgraph(4). Enable the base netgraph code with the NETGRAPH option.
# Individual node types can be enabled with the corresponding option
# listed below; however, this is not strictly necessary as netgraph
# will automatically load the corresponding KLD module if the node type
# is not already compiled into the kernel. Each type below has a
# corresponding man page, e.g., ng_async(8).
options NETGRAPH #netgraph(4) system
#
# 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 'fddi' pseudo-device provides generic code to support FDDI.
# The `sppp' pseudo-device serves a similar role for certain types
# of synchronous PPP links (like `cx', `ar').
# 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.
# The `disc' pseudo-device implements a minimal network interface,
# which throws away all packets sent and never receives any. It is
# included for testing purposes.
# The `tun' pseudo-device implements the User Process PPP (iijppp)
# The `streams' pseudo-device implements SysVR4 STREAMS emulation.
#
# The PPP_BSDCOMP option enables support for compress(1) style entire
# packet compression, the PPP_DEFLATE is for zlib/gzip style compression.
# PPP_FILTER enables code for filtering the ppp data stream and selecting
# events for resetting the demand dial activity timer - requires bpfilter.
# See pppd(8) for more details.

#
# 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.
#
# 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 sends
# logged packets to the system logger. IPFIREWALL_VERBOSE_LIMIT
# limits the number of times a matching entry can be logged.
#
# WARNING: IPFIREWALL defaults to a policy of "deny ip from any to any"
# and if you do not add other rules during startup to allow access,
# YOU WILL LOCK YOURSELF OUT. It is suggested that you set firewall=open
# in /etc/rc.conf when first enabling this feature, then refining the
# firewall rules in /etc/rc.firewall after you've tested that the new kernel
# feature works properly.
#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to
# allow everything. Use with care, if a cracker can crash your
# firewall machine, they can get to your protected machines. However,
# if you are using it as an as-needed filter for specific problems as
# they arise, then this may be for you. Changing the default to 'allow'
# means that you won't get stuck if the kernel and /sbin/ipfw binary get
# out of sync.
#
# IPDIVERT enables the divert IP sockets, used by ``ipfw divert''
#
# IPSTEALTH enables code to support stealth forwarding (i.e., forwarding
# packets without touching the ttl). This can be useful to hide firewalls
# from traceroute and similar tools.
#
# TCPDEBUG is undocumented.
#
options MROUTING # Multicast routing
options IPFIREWALL #firewall
options IPFIREWALL_VERBOSE #print information about
# dropped packets
options IPFIREWALL_FORWARD #enable transparent proxy support
#options IPFIREWALL_VERBOSE_LIMIT=100 #limit verbosity
#options IPFIREWALL_DEFAULT_TO_ACCEPT #allow everything by default
options IPV6FIREWALL #firewall for IPv6
options IPV6FIREWALL_VERBOSE
options IPDIVERT #divert sockets
#options IPFILTER #ipfilter support
#options IPFILTER_LOG #ipfilter logging
options IPSTEALTH #support for stealth forwarding
# The following options add sysctl variables for controlling how certain
# TCP packets are handled.
#
# TCP_DROP_SYNFIN adds support for ignoring TCP packets with SYN+FIN. This
# prevents nmap et al. from identifying the TCP/IP stack, but breaks support
# for RFC1644 extensions and is not recommended for web servers.
#
# TCP_RESTRICT_RST adds support for blocking the emission of TCP RST packets.
# This is useful on systems which are exposed to SYN floods (e.g. IRC servers)
# or any system which one does not want to be easily portscannable.
#
options TCP_DROP_SYNFIN #drop TCP packets with SYN+FIN
options TCP_RESTRICT_RST #restrict emission of TCP RST
# ICMP_BANDLIM enables icmp error response bandwidth limiting. You
# typically want this option as it will help protect the machine from
# D.O.S. packet attacks.
#
options ICMP_BANDLIM
# DUMMYNET enables the "dummynet" bandwidth limiter. You need
# IPFIREWALL as well. See the dummynet(4) manpage for more info.
# BRIDGE enables bridging between ethernet cards -- see bridge(4).
# You can use IPFIREWALL and dummynet together with bridging.
options DUMMYNET
#options BRIDGE
#####################################################################
# 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, and MFS --- cannot
# currently be demand-loaded.) Some people still prefer to statically
# compile other filesystems as well.
#
# NB: The NULL, PORTAL, UMAP 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 MFS #Memory File System
options NFS #Network File System
# The rest are optional:
options FFS_ROOT #FFS usable as root device
# Soft updates is technique for improving file system speed and
# making abrupt shutdown less risky. It is not enabled by default due
# to copyright restraints on the code that implement it.

# `flags' for serial drivers that support consoles (only for sio now):
# 0x10 enable console support for this unit. The other console flags
# are ignored unless this is set. Enabling console support does
# not make the unit the preferred console - boot with -h or set
# the 0x20 flag for that. Currently, at most one unit can have
# console support; the first one (in config file order) with
# this flag set is preferred. Setting this flag for sio0 gives
# the old behaviour.

>Description:
The scsi sub system freezes the whole system when under load. The system
just locks and the led of the host adapter stays on. No logfile entry
gives a hint. The system even doesn't react to pressing ctl-alt-del.
>How-To-Repeat:
Just booting the X server or inn is enough to freeze the system. If it
survives that it usually frezzes when login into kde. Strangely enough
a make -j 12 world doesn't trigger a freeze.
>Fix:
Don't know. I'm going back to 4.1 which didn't behave that strange.
