Message from syslogd

I'm recieving from time to time such messages:

Message from syslogd@localhost at Sat Jul  8 18:29:58 2006 ...
localhost kernel: Disabling IRQ #17

What could cause such messages? How can I at least disable these messages which are posted on all terminals?

Hi...

Interrupt Request Line (IRQ) are hardware lines over which devices can send interrupt signals to the microprocessor.

Therefore, what I probably make out from the output is that a device has been assigned an IRQ which is clashing with the IRQ of another device, therefore the kernel disables that IRQ and logs the output.

Thanks, but how can I figure out what divices are using IRQ 17

gautamatul82 · July 20, 2006, 9:03am

You can try and use the command --

dmesg | grep "irq 14"

OR

dmesg | grep "IRQ 17"

See if you can get some useful output.

ok, what I've had:

$ dmesg | grep -i "irq.*17"
ACPI: PCI Interrupt 0000:00:0a.0[A] -> GSI 18 (level, low) -> IRQ 17
saa7134[0]: found at 0000:00:0a.0, rev: 1, irq: 17, latency: 32, mmio: 0xe6001000

I have tv tuner on irq 17, but why I'm recieving

?
any ideas??

Hey.....

How did you notice that you have IRQ #17 is assigned to the TV Tuner ???

saa7134 is a chipset of the tuner

Hi Hitori,

You can try adding the following to the /etc/grub.conf file -----

kernel /vmlinuz-2.4.20-8bigmem ro root=LABEL=/ irqpoll

See, if that helps you out and resolves this problem.

Any other ideas Any help is appriciated

Are you certain you tried irqpoll correctly?

Press escape during the grub menu and select the kernel you'd like to boot and press "e" to edit the boot options. Once there you can simply include "irqpoll" at the end of the boot options (make sure there's a space between / and irqpoll).

If that doesn't work, try booting with noacpi or acpi=off.

Hitori · July 27, 2006, 2:01am

By the way what does acpi do??
(I do not want to turn off some useful functions)
