    Lenovo S12 freeze

    Hi,

    a few days ago i bought a Lenovo S12 and installed a crypted Ubuntu Karmic on it.
    The problem is, that the system freezes really often. But when i hit a key or move the mouse the system moves on.

    I have the Lenovo S12 with Atom processor and Intel GMA gfx.

    Can anyone help me?

    Best regards,
    MKay

    I have the same problem. Only that I do not use encryption.

    It happens quite randomly, or at least I couldn't spot a pattern yet. Sometimes even during boot.

    After hitting a key the system resumes as if nothing happened.

    I suspect problems with the power-manager.

    The same problem occurrs on a second s12 of a friend with Jaunty and Karmic Live-CD.
    I also tested a debian live-cd, which shows me a kernel failure message. I used the dialog to send the kernel diagnostic report to the developers
    So maybe its a kernel-problem.

    I did some trial and error and came across the BIOS setting "SATA controller working mode". I changed this from AHCI to Compatibility and the problem seems to be gone for now.

    Give this a try and see if it works.

    It could be pure coincidence for me. As I said this was pure trial and error.
    I have no idea if AHCI could actually be causing this...

    Good luck!
