    Please try changing msleep(1) to udelay(50) in drivers/acpi/ec.c
    Do you have msi-laptop module loaded?
    Please fill a bugreport and attach all the information there.

    Thanks,
    Alex.

    Ok. Will try this. However as I said issue is not easy to reproduce.. So
    I'll just change it and wait a bit.

    > have msi-laptop module loaded?


    No. I don't use it.

    Ok. Will do this soon
