  <dt>Stray interrupt on IRQ 7</dt>
  <dd>It means the interrupt controller reported an unmasked interrupt on IRQ 7,
      but no driver attached to that IRQ `claimed' it.
    <p class="Pp">There are two reasons this can happen:</p>
    <ul class="Bl-bullet">
      <li>In anything other than i386, it would almost always mean that there is
          a driver attached to the IRQ, but it is the wrong driver.</li>
      <li>On i386, there is the more obscure issue of `default IRQ7's. That is,
          when a device asserts an IRQ, but the IRQ is deasserted after the PIC
          latches the interrupt and before the CPU acknowledges it, the PIC just
          flat out lies about which IRQ it was. It is usually due to a
          suboptimally coded driver.</li>
