5.3-release fine with 512MB RAM, reboots at times with 1.5GB (but no panic) - FreeBSD

I have been troubleshooting reboots over the last weekend, I think I might have enough clues now to get some useful hints from an expert. FreeBSD 5.3-release (see dmesg below for details) The problem seems to be with trying to run with 1.5GB vice 512MB of RAM. The system has not had problems so far when I only leave the 512MB stick in. When I add the 1GB stick the system will reboot at specific times, for example, while trying to launch KDE3 or trying to make OpenOffice (always reboots at "Extracting for openoffice-1.1.2-1").

    Default 5.3-release fine with 512MB RAM, reboots at times with 1.5GB (but no panic)

    I have been troubleshooting reboots over the last weekend, I think I
    might have enough clues now to get some useful hints from an expert.

    FreeBSD 5.3-release (see dmesg below for details)

    The problem seems to be with trying to run with 1.5GB vice 512MB of RAM.
    The system has not had problems so far when I only leave the 512MB stick
    in. When I add the 1GB stick the system will reboot at specific times,
    for example, while trying to launch KDE3 or trying to make OpenOffice
    (always reboots at "Extracting for openoffice-1.1.2-1"). I do not see
    any panic in the messages log, the system just silently reboots.

    I initially installed FreeBSD with only the 512MB stick in.

    The memory itself seems fine; memtest86 detects no errors.

    At boot time all the memory is detected:

    real memory = 1610547200 (1535 MB)
    avail memory = 1568432128 (1495 MB)

    Running "memtest all" only seems to find 512MB to use. It evidently
    makes no assumption about how much memory is there, starting by trying
    to malloc 4GB and reducing the amount gradually until it finally
    successfully mallocs 512 MB and eventually manages to lock 413 MB
    (failed due to "insufficient resources" above that). The tests on the
    413 MB do pass.

    I have rebuilt the kernel with VM_KMEM_SIZE_MAX=419430400 as suggested
    in the FAQ. No change.

    Would setting MAXMEM to 1572864 help? I am not sure since the correct
    amount is reported by FreeBSD at boot, and right now trying to make the
    kernel with that option seems to be another case that reboots the
    machine (i.e. the make process itself reboots the machine) so I have not
    tried it yet (guess I would have to remove the 1GB stick to make the
    new kernel and then put it back to try it out).

    Thank you for any help.

    I also find it hard to believe you have a bad mptable. Maybe you could

    I would have to agree that it is a HW issue. The RAM itself may be
    ok, but may have issues with other HW components in your system.

    I too have a similar problem. I have 7 identical systems. all with
    identical MoBo's SCSI hard drives and RAM.

    One machine reboots frequently with 5.3 where with 4.9 it "never"
    rebooted. 6 machines are fine. 1 reboots. I changed memory sticks.
    (which incidentally always pass an extensive memory test). I even
    changed the power supply on the computer.

    The last thing I am going to change is the MoBo. Perhaps it has some
    timing issue discovered only with 5.3. Luckily when I needed 7 MoBos,
    I purchased 8 and have a spare.

    This is mystery, because as I said, 4.9 worked fine on this machine.

    As you noted, 5.3 uses the hardware differently. For example, it uses
    ACPI, which is sometimes buggy as implemented by the mobo
    manufacturer. Try looking for an updated BIOS, disabling ACPI in the
    freebsd boot screen, etc.

    Also make sure you're truly seeing a spontaneous reboot and not a
    panic. Sometimes users are confused about the difference (when
    FreeBSD panics it tells you as such on the console).

    Have you checked your motherboard's manual for allowed memory combinations?

    I was thinking of making the same upgrade, but I looked through the table of
    supported configurations and I noticed that for DDR 400 memory, I should only
    have 1 double-sided stick. As I understand it, most DDR400 memory at 0.5 and
    1GB is currently double-sided.

    Thanks to all who replied. So it seems the consensus is a likely
    hardware issue, and I am leaning that way as well now. I will try the
    suggestion about disabling ACPI however.

    To address some of the other comments, that exact CPU-mobo-memory
    configuration worked fine running Win2000 for many years, so I doubt it
    is the problem per se. Also, I did try the 1GB stick alone yesterday and
    it had similar symptoms as for 1.5 GB.

    I do know where to look for a panic message and there is none.

    About my running Win2000 on this hardware before, I would initially have
    thought that this made a hardware problem improbable, but I used to run
    the computer continually and I guess it's not impossible that there was
    a hardware degradation that was mitigated by the system staying warm all
    the time. The system was mothballed for a few months before my FreeBSD
    install, so the prolonged period at room temperature may have allowed
    some motherboard degradation to get worse. I was led to form that
    hypothesis because I noticed yesterday that there seems to be a relation
    with temperature: I ran burnP6 and crashme concurrently (both ran
    without problem with any memory configuration but I realize that neither
    of these two utilities necessarily stress the system in the way I need)
    and since they ran fine with the 1.5 GB in I tried to start KDE again
    (leaving the stress applications running) and it did bring everything up
    without rebooting. I stopped the system and let it cool down and KDE
    made the system reboot as before after a restart. I guess my next step
    will be to install chm or something like that to monitor the
    temperatures as the system runs, but anyway, it seems this is likely not
    a FreeBSD problem anymore, so I thank you all again for the suggestions
    and will continue troubleshooting the hardware. My immediate guess is
    either the CPU or motherboard.

    Oh yeah, I still wonder thought why "memtest all" only seemed to "find"
    512MB of RAM, but I think it is a side issue at this time.

    Cheers,

    Jean

    I have had odd behavior like you are describing with cheap
    motherboards. I ran all of the memory tests etc, and everything
    passed with flying colors. Despite passing all of the tests I could
    throw at the hardware, windows 2000 was very unstable. We ultimately
    ended up replacing the board.
