i915_driver_irq_handler: irq 42: nobody cared

I'm getting spurious interrupts leading to disabling the interrupt:
42: 1916853 2471662 PCI-MSI-edge i915 at pci:0000:00:02.0
irq 42: nobody cared (try booting with the "irqpoll" option)
Pid: 20716, comm: virtuoso-t Not tainted 3.3.0-next-20120326_64+ #1673
It is not new, but now I can reproduce it more-or-less reliably after an
hour or so. It usually happens when playing a game using wine.
Do you want me to dump some registers when IRQ_NONE is returned from the
ISR? As this is MSI, nobody else can sit there.
