Thread: System freezes for no obvious reason

    Default System freezes for no obvious reason

    Hi everyone!

    A couple of days ago I upgraded from 13.2 to TW, since 13.2 didn't have the hardware support for many devices on my laptop. I'm perfectly happy with TW, except... the entire system freezes quite frequently. It doesn't seem to depend on the programs that are running at the moment, in fact I can't see any reason why my laptop stops responding every now and then. Suddenly I can't move the mouse any more, the cooler starts blowing like crazy and all I can to is to stop the power supply.

    If you have any idea how I could track this issue down that would be much appreciated

    Let me know if I should give you any more detailed specs.

    Many thanks in advance!

    Leave a terminal with "top" running. When this happens, take a look to
    see if something is using much cpu.

    Thanks for your hint, Carlos!

    THIS IS SO WEIRD!!!

    Whenever I have my 'trap' set up, either a konsole window with top or the GUI of the system activity monitor, everything remains perfectly stable. However, as soon as I close these windows, it doesn't take long until the system freezes again.

    Has anyone else encountered any creepy goblins inside Tumbleweed? Artificial intelligence?

    Well tumbleweed is cutting edge. And with cutting edge you expect to bleed.

    That is odd maybe time to test the RAM let test run over night

    Years ago, I had a very weird issue: if I did not use the mouse or
    keyboard, after a while everything froze, meaning that every task would
    stop, the clock would stop, etc. However, touch a key or move the mouse,
    and everything went normal. The clock jumped seconds, or many minutes,
    depending on how long it had stayed that way.

    We never found the cause; yes, there was a bugzilla, because it happened
    after a kernel update.

    The cure was to have another machine continuously ping this one. Network
    activity triggers interrupts, and the machine responded to them. It was
    actually sitting idle, waiting for something to be done, conserving
    energy, kind of.

    Eventually (years) I bought another desktop machine.

    Interesting what sort of bugs one can get... Anyway, I've now always had my watchdog active in the background. When I switched on my laptop earlier on I forgot to open it, though. Nevertheless, everything's remained stable for a couple of hours already - seems like the issue has fixed itself Many thanks for your help, you two!
