    kernel BUG: soft lockup - CPU stuck for 23s!

    Hi, thanks for reading this.

    Basically, my machine is sort of half crashing yielding error messages in the
    kern.log, and I'm looking for advice on what to try next. When there's a
    crash, some of the applications are still working, but the machine is very
    slow, and the crashed application is unresponsive; also the machine will not
    shutdown properly necessitating application of the Reset button.

    Here's the background:

    I recently installed Xubuntu 13.10 from DVD (checksummed, downloaded
    images I burned to DVD).

    I'm getting a series of crashes all of the type "BUG: soft lockup - CPU stuck".
    An interesting feature of my crashes is that the crash is not always associated
    with the same user-space software (often firefox, sometimes "irqbalance",
    sometimes samba).

    The computer is lightly used for e-mail, websurfing, and sharing files through
    samba, on a local home network.

    I've done the usual things:
    1 - I've googled extensively
    2 - I've upgraded the BIOS
    3 - I've run memtest
    4 - I've tried running "untainted" by using the "Nouveau" Nvidia driver
    (#4 made no difference to my problem, I still got the crashes, so I switched
    back to the closed-source Nvidia drivers for performance reasons.)

    Here are the log entries corresponding to some of these crashes:

    Re: kernel BUG: soft lockup - CPU stuck for 23s!

    Hi.
    I haven't had any replies to my post.
    Anybody got any ideas on what to try next?

    I have experimented with adding "acpi=off noapic nolapic" to the kernel options, and these stop the crashes (suggesting to me that there's something wrong with the SPINLOCK code). But when I boot this way these kernel options mean that I am running my dual-core CPU as a single core, so things are SSSLLLOOOWWW.

    Anyway, here's another crash, this one while I was using the open-source "nouveau" nVidia drivers...

    I think i have seen that error before, are you overclocking? this can be caused by a unstable overclock

    Hi - thanks for your suggestion!

    I have never over-clocked this machine, but I have experimented with the various clock modes in my attempts to make this machine more stable. For example, in the BIOS I have tried "Spread Spectrum", "Auto" clocking, and "Manual" clocking (in manual mode I just used the BIOS default values). I get crashes in all three modes.

    Re: kernel BUG: soft lockup - CPU stuck for 23s!

    i would suggest researching how to OC your CPU, possibly getting help on overclockers.com
    i assume you computer is out of warranty
    is is also possible your PSU is not giving the CPU enough power
    it probably just needs a little more vcore, hopefully that will get the CPU stable, a CPU on stock settings should be stable, if not it is defective, but you may be able to compensate with a little above stock voltage

    I've been googling extensively and I think you might be on to something. I'm going to experiment and I'll report back. Thanks for the idea!

    Re: kernel BUG: soft lockup - CPU stuck for 23s!

    it is possible your motherboard is getting auto values wrong, look up the cpu on cpuworld for the specs you will need when using manual in your bios
    sensors is a very useful command
    cat /proc/cpuinfo will also help you out

    Re: kernel BUG: soft lockup - CPU stuck for 23s!

    In the end I slowly became suspicious of the power supply in this computer. It is hard to quantify exactly why, but the suggestions from "pqwoerituytrueiwoq" got me looking at the voltage levels provided by the "sensors" linux command-line program, and the voltages reported by the BIOS, and somehow I decided that it was worth replacing the power supply.

    I bought a small (500W) new power supply made by what I feel is a reputable company and made the swap.

    GREAT NEWS: After replacing the power supply, the crashes completely stopped! I wanted to wait a while just to be sure, but it is now a few weeks since the new powersupply went in, and I haven't had a single crash since. The power supply is not something that I would normally worry about, but in this case it totally fixed my problem.

    Thanks to those who read my post, and especially to those who responded.

    I'm glad you got it sorted out. This proves once again that error messages in Linux are not helpful when you have a hardware problem. Your lack of finding answers on google and lack of forum responses also point to a hardware problem because a kernel or software problem would be repeatable and probably fixed by now.

    There are many power supplies that are made of catfood.
