Hello!
I upgraded this machine yesterday to the latest -stable. It rebooted
fine, but crashed shortly afterwards. The last message in the log is
Jun 1 19:07:20 murlo ntpd[107]: kernel pll status change 2041
Jun 1 19:13:13 murlo /murlo: Copyright (c) 1992-2000 The FreeBSD Project.
It then worked for some time, but crashed again promptly:
Jun 1 19:19:05 murlo ntpd[107]: kernel pll status change 2041
Jun 1 19:50:32 murlo /murlo: Copyright (c) 1992-2000 The FreeBSD Project.
It has now been up for almost 14 hours and appears fine. The pll
status change message appeared again without ill effects:
Jun 1 19:56:22 murlo ntpd[107]: kernel pll status change 2041
Jun 1 20:58:30 murlo ntpd[107]: time reset -0.183257 s
Jun 2 00:06:27 murlo ntpd[107]: time reset -0.143080 s
[...]
The machine was rock-solid under 3.4-STABLE, but I upgraded to
4.0-STABLE in the end of April to get PPPoE. It started crashing once in
two weeks :( I upgraded again yesterday... It uses the wd driver,
because the ata one does not work with one of the disks.
Any suggestions? The kernel config file and dmesg output are attached.
TIA,
-mi

Content-Disposition: attachment ; filename="MURLO"
#
# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family based IBM-PC and
# compatibles.
#

#
# This is the ``identification'' of the kernel. Usually this should
# be the same as the name of your kernel.
#
ident MURLO
#
# The `maxusers' parameter controls the static sizing of a number of
# internal system tables by a complicated formula defined in param.c.
#
maxusers 12
#
# The `makeoptions' parameter allows variables to be passed to the
# generated Makefile in the build area.
#
# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
# after most other flags. Here we use it to inhibit use of non-optimal
# gcc builtin functions (e.g., memcmp).
#
# DEBUG happens to be magic.
# The following is equivalent to 'config -g KERNELNAME' and creates
# 'kernel.debug' compiled with -g debugging as well as a normal
# 'kernel'. Use 'make install.debug' to install the debug kernel
# but that isn't normally necessary as the debug symbols are not loaded
# by the kernel and are not useful there anyway.
#
# KERNEL can be overridden so that you can change the default name of your
# kernel.
#
makeoptions CONF_CFLAGS=-fno-builtin #Don't allow use of memcmp, etc.
#makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols
makeoptions KERNEL=murlo #Build kernel "foo" and install "/foo"
#
# 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.
#
#options MAXDSIZ="(256*1024*1024)"
#options DFLDSIZ="(256*1024*1024)"
#
# BLKDEV_IOSIZE sets the default block size used in user block
# device I/O. Note that this value will be overriden by the label
# when specifying a block device from a label with a non-0
# partition blocksize. The default is PAGE_SIZE.

# The `ppp' pseudo-device implements the Point-to-Point Protocol.

# The `disc' pseudo-device implements a minimal network interface,
# which throws away all packets sent and never receives any. It is

#
# MROUTING enables the kernel multicast packet forwarder, which works

# IPFIREWALL enables support for IP firewall construction, in

#
# 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_type=open
# in /etc/rc.conf when first enabling this feature, then refining the

#
# IPFIREWALL_DEFAULT_TO_ACCEPT causes the default rule (at boot) to

# 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''

#
# TCP_RESTRICT_RST adds support for blocking the emission of TCP RST packets.

#
options TCP_DROP_SYNFIN #drop TCP packets with SYN+FIN

# ICMP_BANDLIM enables icmp error response bandwidth limiting. You

# Mandatory ISA devices: isa, npx
#
device isa
#
# Options for `isa':
#
# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
# This option breaks suspend/resume on some portables.
#
# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated
# versions.
#
# MAXMEM specifies the amount of RAM on the machine; if this is not
# specified, FreeBSD will first read the amount of memory from the CMOS
# RAM, so the amount of memory will initially be limited to 64MB or 16MB
# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
# then attempt to detect the installed amount of RAM. If this probe
# fails to detect >64MB RAM you will have to use the MAXMEM option.
# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

# The flags fields are used to enable the multi-sector I/O and
# the 32BIT I/O modes. The flags may be used in either the controller
# definition or in the individual disk definitions. The controller
# definition is supported for the boot configuration stuff.
#
# Each drive has a 16 bit flags value defined:
# The low 8 bits are the maximum value for the multi-sector I/O,
# where 0xff defaults to the maximum that the drive can handle.
# The high bit of the 16 bit flags (0x8000) allows probing for
# 32 bit transfers. Bit 14 (0x4000) enables a hack to wake
# up powered-down laptop drives. Bit 13 (0x2000) allows
# probing for PCI IDE DMA controllers, such as Intel's PIIX
# south bridges. Bit 12 (0x1000) sets LBA mode instead of the
# default CHS mode for accessing the drive. See the wd.4 man page.
#
# The flags field for the drives can be specified in the controller
# specification with the low 16 bits for drive 0, and the high 16 bits
# for drive 1.
# e.g.:
#device wdc0 at isa? port IO_WD1 irq 14 flags 0x00ff8004
#
# specifies that drive 0 will be allowed to probe for 32 bit transfers and
# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
# allowed to probe for 32 bit transfers, but will allow multi-sector
# transfers up to the maximum that the drive supports.
#
# If you are using a PCI controller that is not running in compatibility
# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)

#device wd5 at wdc2 drive 1
#
#device wdc3 at isa? port 0 flags 0xa0ffa0ff
#device wd6 at wdc3 drive 0
#device wd7 at wdc3 drive 1
#
# Note that the above config would be useful for a Promise card, when used
# on a MB that already has a PIIX controller. Note the bogus irq and port
# entries. These are automatically filled in by the IDE/PCI support.
#
# This driver must be commented out because it is mutually exclusive with
