modprobe messages

[Dark]

This isn't a problem exactly.

I just like to watch /var/log/messages to see what is going on with my system and to be aware of any problems.

First, I noticed 2 particular errors occuring on a regular basis-

Mar 13 01:10:15 fedora modprobe: modprobe: Can't locate module sound-slot-1
Mar 13 01:10:15 fedora modprobe: modprobe: Can't locate module sound-service-1-0
Mar 13 01:10:15 fedora modprobe: modprobe: Can't locate module sound-slot-1
Mar 13 01:10:15 fedora modprobe: modprobe: Can't locate module sound-service-1-0
Mar 13 01:10:23 fedora modprobe: modprobe: Can't locate module sound-slot-1
Mar 13 01:10:23 fedora modprobe: modprobe: Can't locate module sound-service-1-0


Just like that. Sound works perfectly fine despite these errors.


The other "error" only occurs when I reboot-

Mar 13 01:08:25 fedora modprobe: modprobe: Can't locate module char-major-10-134

This isn't really a problem, but I see modprobe complaining and I would like to fix it but I can't.

I have looked at /etc/modules.conf and sound-slot-1, sound-service-1-0, and char-major-10-134 are NOT listed at all, so I'm not sure why it's even trying to load those modules.

[skoona]

The files /usr/src/linux-2.4.22-1.2174.nptl/Documentation/devices.txt
list all the device Linux can use. Its a goodd place to look up char-major-10-134.

char-major-10-134 is ' /dev/apm_bios Advanced Power Management BIOS'

I think this suggests that either
1. your mobo does not support APM power management and your system was told to initialize APM -causing this message,
2. or that your Kernel does not have support for it and some other service made a call looking for it - causing this message.

You can most likely make this message go away by adding a boot parm to you kernel statement in grub.conf. A parm like 'apm=off'. Be sure that's what you want to do first.

APM's counterpart is ACPI. One or both of these power management schemes can be enabled.

module sound-slot-1 = refers to a second sound card (-0 is first). Maybe you have on-board sound and a pci sound card. If true, these messages may go away if you diable (via bios) the motherboard (mobo) sound devices.

TV Tuner cards, which need audio service, may have contributed to this message. Hard to know without a 'lsmod' and 'lspci -v' listing.

You might want to research 'modules.conf' vs 'modprobe.conf'. both in the /etc dir.

It's a Tyan Tiger 2460 board, which has no onboard sound. I have most unused devices disabled in the BIOS- parallel port, serial ports, IDE controller, floppy controller. I just enabled ACPI in BIOS to see if it would make a difference but there was no apparent change, as of the last reboot there are new error messages the same as before.

Here are the lsmod and lpci - v listings.

As you can probably see, I have a Geforce FX 5200 AGP card, an ensonique AudioPCI sound card, an Intel Pro/100 NIC, and an LSI Ultra160 SCSI card.

I've got the same 10-134 message in my syslog. Plus I know I have APM=OFF as a kernel parm.

It appears that the file '/etc/init.d/apmd' does a 'modprobe apm' once during system startup. This could be the cause. I cannot say for sure. I will comment out that line on my machine ans see. Hold on.

So now I am out of ideals for the moment. I will come back to it later.

Util then the other message is OSS related. These two URL contain useful information to guide you. And I will look at it when I come back.

When X first starts up it attempts to load module apm_bios. This definitately causing the modprobe message (unless apm_bios module is found because 'CONFIG_APM=Y' in your last kernel config)

What to do to turn it off? Don't know yet! Looking through /etc/X11/XF86Config is the place to start.

[skoona]

Add this line to /etc/modules.conf

alias char-major-10-134 off

-- or --

alias char-major-10-134 null


OFF causes modprobe to IGNORE the request and NULL causes the request to succeed but never loads the modules. I think OFF is safer.

As for the other message they can be handled the exact same way; when your sure they are not errors or needed.

sound-slot-1 is the name of a second sound card, some program likely tried to access/open a device like /dev/adsp0 and caused this message. Again off or null will handle this

Hope this helps.

Thanks, I'll give it a try and see how things go.

Has this been resolved?
