Exclamation Message from syslogd

I'm recieving from time to time such messages:
Code:
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?

Note:
$ uname -a
Linux localhost.localdomain 2.6.16-1.2096_FC5 #1 Wed Apr 19 05:14:36 EDT 2006 i686 athlon i386 GNU/Linux

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.

You can try and use the command --

dmesg | grep "irq 14"

OR

dmesg | grep "IRQ 17"

See if you can get some useful output.
