Subject: Re: [3.9-rc1] irq 16: nobody cared (was [3.9-rc1] very poor interrupt responses)

I have the same problem on my Lenovo T500. I think the graphics card is
involved.
This laptop has "hybrid graphics" - one Intel GMA 4500MHD and one ATI
Mobility Radeon HD 3650. When I boot with the Intel card, I get "irq 16:
nobody cared" during boot, not when I boot with the ATI card.
And /proc/interrupts are surely different with the two cards. Look at
the irq 16 line:
