Oops is in sound/pci/intel8x0.c::snd_intel8x0_update(), part of
the interrupt handler:

Line 751:

        ichdev->position += step * ichdev->fragsize1;
        if (! chip->in_measurement)
                ichdev->position %= ichdev->size;

ichdev->size is 0. Interrupt happened upon request_irq().

Does chip->in_measurement need to be reset because this is a
crashdump kernel?
