    PCH poison interrupt (Natty)

    Dear all,

    After updating to 2.6.39-0-generic (running Natty on a Lenovo X220),
    I have the following error (usually after attempting to or resuming
    from suspend):

    [drmch_irq_handler] *ERROR* PCH poison interrupt

    The 2.6.38 kernel produces random freezes which are now gone. However,
    this problem also makes the system completely unresponsive and requires
    a reboot. Suspend/resume was working fine with 2.6.38.

    Any help is appreciated.

    This may help you. There's a patch in the thread below if you feel like recompiling but looks like it should be fixed in 2.6.40 otherwise.

    Hi!

    I have seen this patch as well, but have not managed to compile the driver.

    Also, I have installed the 3.0.0 kernel (aka 2.6.40), but the issue persists
    (looking at the intel driver source, the patch has not been included yet).

    Best

    Martin
