localhost kernel: Disabling IRQ #11


I keep getting these popping up on my screen, only the IRQ # tends to vary.
I´ve never seen this kind of behaviour before.
Perhaps stating the obvious - this is a symptom of an interrupt request
and/or kernel driver problem.  Running "tail -f /var/log/messages" in a
root shell console and checking the output after seeing the message, or
doing "dmesg" when it happens should give more info.  May be able to
change BIOS settings (such as PNP OS or IRQ assignments - depends on
BIOS), try an older/newer kernel (did it just start happening after an
update?), or change the slots for PCI cards (any recent hardware
changes?).

A google on "Message from syslogd kernel Disabling IRQ" (without the
quotes) will perhaps give some more ideas.

Well, I´m not even sure if or how much I should be concerned.
I mean, it doesn´t appear to be hindering the functionality of anything I do or am doing at the time the message appears.
I wondered if it was a security issue or something....
I just did this fresh install of FC5 last weekend, and have done no updates.
As per usual, I´ve spent most of my copious spare time over the past week reconfiguring stuff to my likeing, adding software (mostly with yum, some just by DL ing the rpms and installing myself) that doesn´t come on the install, etc..
But haven´t done a yum update on anything.
I DLed yumex yesterday, and I think it´s choosing to update stuff on it´s own....Not sure. I only like using it because it makes it easy to see what´s on the repo and pick stuff up. (DLed a bunch of nifty games last night! I didn´t even know they existed or were available until yumex offered them up.)
Normally I just use yum at the command line, though.
I haven´t seen the msg since last night, so opened up /var/log/msgs in a text editor and dug around a bit.
I found the message, and am pasting in a bit before and after...
This is the most recent on I received. I know I´ve seen irq #16, and at least one other number in the past couple of day. It might be nearly impossible to figure out what I´ve done to affect this, after all, I´ve done a lot of configuration.
I believe this started only two or three days ago.
Does this shed some light, perhaps? (it´s as good as Chinese to me...which is not one of the languages I speak):

Any further assistance deeply appreciated.

The "audit" messages here don't include any denials and just indicate
that you have an old SELinux policy (probably not updated since
installing the OS).

Have you tried booting with the "irqpoll" option as the message
suggests?


I haven´t even the slightest idea what that entails or how it would be done, to tell the truth...
Would you suggest that I yum update SELinux, or something?
