Linux interrupt problem

[REBELinBLUE]

When I start X I get

(EE) NVIDIA(0): The NVIDIA kernel module does not appear to be receiving
(EE) NVIDIA(0): interrupts generated by the NVIDIA graphics device.
(EE) NVIDIA(0): Please the the FREQUENTLY ASKED QUESTIONS section in
(EE) NVIDIA(0): README for additional information.

Now before anyone says "use search" I know the solution about passing one of the following

pci=noacpi (doesn't work for me)
pci=biosirq (doesn't work for me)
noapic (works)
acpi=off (works)

or disabling PnP OS in bios or setting assign irq to vga to true, neither option I have.

The problem is when I set those options the majority of my USB ports are disabled, including the internal one my wifi is connected to.

Does anyone know another way around this because I need those USB ports.

[chunkey]

what does /proc/interrupts, dmesg and lspci -v look like with acpi & apic enabled?

(Have you ever tried newer/older kernels, or nvidia's 7676 driver?)
(Maybe a BIOS flash can also help...)

[REBELinBLUE]

The BIOS is the most recent version, I have also tried the latest NVIDIA drivers with the same outcome. Will get the command outputs and post them in a little while

[Thunderbird]

Not sure if the card likes to share an interrupt with the USB controller, try to unload that driver and see if it works then.

Thanks chunkey for the suggestion, read through the files I created and saw the line

irq 19: nobody cared (try booting with the "irqpoll" option.

So I did, and it worked Now to try and get the wifi to actually work

[chunkey]

irq 19: nobody cared (try booting with the "irqpoll" option.

Hmm, do you know what's on irq 19?
(a complete dmesg & lspci -v)



do these kernel-parameters (noirqdebug, or irqfixup) the same thing as irqpoll?

IRQ 19 is

0000:01:06.1 USB Controller: NEC Corporation USB (rev 43) (prog-if 10 [OHCI])
	Subsystem: Siig Inc: Unknown device 131f
	Flags: bus master, medium devsel, latency 32, IRQ 19
	Memory at e6001000 (32-bit, non-prefetchable) [size=4K]
	Capabilities: [40] Power Management version 2

Which oddly enough is my USB card, not my nForce 2 onboard USB ports which are the ones which didn't work

Will give those other parameters a try later, any reason to use them over irqpoll?

??? Weird indeed.
(Maybe, you should file a bug-report)

well, PERFORMANCE!
