    Laptop locks up under heavy load

    I have a gateway cx210.
    Intel Core 2 T7200 2ghz
    ATI radeon mobility x1400

    When running CPU intensive tasks or games my laptop will lockup. The screen will freeze. Sometimes sound continues to function but other times the sound will start looping the previous second or so. The computer becomes quite hot to the touch but not 'cookin' hot.

    The only way to recover is a hard reboot.

    Re: Laptop locks up under heavy load

    *bump*
    Problem is still occurring after several kernel updates and has been occurring for quite a while. I have identified it as a soft lock-up. The cause remains unknown.

    the following is the syslog of one such incident.
    Code:

Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

    As far as I can tell these events occur in a similar manner every time.

    Any and all help is truly appreciated.

    Re: Laptop locks up under heavy load

    It looks like it's a problem with the ATI driver. I would see if you can find a newer version and see if that helps.
    Don't try to make something "fast" until you are able to quantify "slow".

    Thanks, updating the ATI drivers helped alot. The problem is not entirely resolved but my system no longer locks up at the drop of a hat.

    Re: Laptop locks up under heavy load

    Graphics drivers are the #1 cause of system lockup and crashes. Keep on doing kernel updates and graphics driver updates, and eventually these problems will resolve themselves.

    In the meantime, if your computer does freeze up again, you can safely shut it down with the magic sysreq key:

    http://en.wikipedia.org/wiki/Magic_SysRq_key

    Just press and hold alt+sysrq, then while holding them, type (slowly) r e i s u b and your computer will reboot, even if it's frozen from the graphics driver freaking out again.

    Also, you might want to double-check and make sure that your temperature is okay and nothing's overheating, as that could also cause this type of problem.
