The previous kernel never gave any type of messages like these …
I notice that IRQ came up with nvidia AND the last time I saw such a message was after loading a newer kernel and having an old proprietary nVIDIA video driver loaded. I updated the video driver to the latest and the kernel error went away.

I get a similar irq message during boot with a 6100 chip set. Once the boot
finishes, the Nvidia driver has re-assigned that function to another irq and
something else is using the orginally bad one. The whole sequence indicates
to me that the BIOS is initializing the Nvidia chipset in a way that
conflicts with something in the kernel which disables the offender and the
Nvidia driver later assigns a non-conflicting irq. Check the disabled irq
after the bootup is fully complete and see if something is using it.
i don’t have any advice on repairing the problem, but i can add broader depth to the discussion in that the same type of kernel message indicating a irq disable happens also using the newer fglrx driver.
Usually the kernel message happens after a few seconds of starting a video, but it will also occur if you run fgl_glxgears. Up until now i suspected a problem with the driver.
i have a 11.2 (2.6.31) and an 11.4 (2.6.37) installed on this machine and both environments exhibit this behavior. Nothing seems broken by the reallocation… just the message is logged.
