Subject: i915_driver_irq_handler: irq 42: nobody cared
Date: Tue, 27 Mar 2012 10:40:03 +0200	[thread overview]
Message-ID: <4F717CE3.4040206@suse.cz> (raw)

Hi,

I'm getting spurious interrupts leading to disabling the interrupt:
 42:    1916853    2471662   PCI-MSI-edge      i915@pci:0000:00:02.0

The message:
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.

thanks,
