Annoying console message: Disabling IRQ #XXX.

I met a strange console message: Disabling IRQ #217 every half hour once. I search the google and put "noapic & acpi=off" in grub.conf, but it doesn't work. The message will change to "Last message repeated N times", when I singly use noapic, the warning changes to IRQ #5, when I use acpi=off, it changes to IRQ #193. Does it have any method to avoid showing this message as I know it doesn't effect the system?

does anyone can help?

Don't use the acpi=off boot option. That will cause more problems than it will fix. It could help during the initial installation if the install program will otherwise lock up, but on modern computers you won't have interrupt support for some of your devices if you disable acpi support.

Are normally logging in as root? I don't think other users would get these messages.

Look in /etc/syslog-ng.conf or /etc/syslog-ng/syslog-ng.conf.

Code:

# Enable this, if you want that root is informed immediately,

# e.g. of logins:

#

#destination root { usertty("root"); };

#log { source(src); filter(f_alert); destination(root); };

My system has these lines commented out. Do you have something similar which sends messages to root's tty? The "filter(...)" part may be different.

other user will also receive this message once half hour. Not only root user.

I only have syslog.conf in my /etc directory. And the code are:
# Log all kernel messages to the console.
# Logging much else clutters up the screen.
#kern.* /dev/console

# Log anything (except mail) of level info or higher.
# Don't log private authentication messages!
*.info;mail.none;authpriv.none;cron.none /var/log/messages

# The authpriv file has restricted access.
authpriv.* /var/log/secure

# Log all the mail messages in one place.
mail.* -/var/log/maillog

# Log cron stuff
cron.* /var/log/cron

# Everybody gets emergency messages
*.emerg *

# Save news errors of level crit and higher in a special file.
uucp,news.crit /var/log/spooler

# Save boot messages also to boot.log
local7.* /var/log/boot.log

can I use 'mesg n' to avoid seeing it? where should I put it to set it permanent?

I think this is the source:

Code:

# Everybody gets emergency messages

*.emerg *

I'm afraid that if you disable all emergency messages to all users, you may miss more important ones. You might want to look at what the root cause of the message is. Look in /var/log/messages for a matching message. Is it an emergency message?
You could put the "mesg n" in /etc/profile ( or /etc/profile.local if /etc/profile sources it ).

Run "mesg" by itself to see what the current settings are. I don't know if "mesg n" will block messages from syslog however but it's worth a try.

It seems that 'mesg n' doesn't do any help. I have looked up to redirect the *.emerg to /dev/null from google and it told me that it won't make any sense.
The message in /var/log/message repeated XXX times

Does it mean that there is some hardware conflict with the OS? thanks:)

What devices do you have plugged in? I can't boot up my computer with a flash card inserted in the slot. I can insert it afterwards.

You might try disconnecting unneeded devices such as external drives or flash devices and see if the problem persists.
Look at the output of dmesg or boot.log to see when the first indication of a problem is. Is is associated with loading a particular kernel module?

Look in the text file kernel-parameters.txt in the kernel source. There are several noacpi options that offer more granularity.
What is the make of your mobo? Does google turn up similar messages for that motherboard?

Try a different kernel version.

Look at "grep 'irq=127' /etc/modprobe.conf" and "lspci -v | grep 'IRQ 127'"

It would entail recompiling your kernel enabling debugging for usb and file system access.

I was hoping the modinfo would show possible interupts for a device.

Code:

modinfo uhci_hcd

I didn't know that Linus' nickname was Frodo Rabbit.

this is what shown in lspci of IRQ 217, it's the sata hard disk! what should I do to disconnect this?

Code:

00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) (prog-if 8f [Master SecP SecO PriP PriO])

        I/O ports at fea0 [size=16]

And I have tried several ways to avoid showing this message,but all failed. Is there any command can help me to prevent seeing it?As it do no harm to the system. Thanks.
