Still seeking an answer... Module loading dilema...

Another day... new gentoo problem! I am bothered by some of my dmesg printout that I've been unable to correct:

I eliminated one of the bothersome line in my dmesg output:

I feel like this is a one way convesation... but what I want to find out is...

Why would my 2.4 kernel try to load software (i810 TCO timer) when I don't have the appropriate hardware (Intel 810) in my system?

I can't believe the answer is so difficult... I sure would like some help, though!

Thanks...

Chandra

Your on the right track, you need to add the name of the i810 TCO watchdog timer module ( i8xx_tco ) to /etc/hotplug/blacklist. Hopefully that will work. Check out what I found in the modules help entry:

cd into your /etc/modules.d directory.

Then do:

Thanks for the suggestion, Sith_Happens.... I'll give it a try

Sure thing, I'm just sorry your topic got lost in the shuffle for so long. Again hope it works.

BTW: Is your nickname from Dr. Chandra from 2001: A Space Odyssey and 2010: Odyssey Two? Or is it just your name?

I'm sorry, I got the name wrong for the i810-tco driver.

It's really called i8xx_tco.

In the kernel config it's CONFIG_i8XX_TCO.

After you run 'make menuconfig' to set up
your kernel, the option to enable this is
under Device Drivers -> Character Devices ->
Watchdog Cards -> Watchdog Timer Support.

Your kernel was obviously compiled with
'Watchdog Timer Support' checked. The i8xx_tco
part was probably built as a module, along with
everything else in that tree.

I think you should still be able to find the
i8xx part in your /etc/modules.d directory.
( grep i8xx * )

That should return the bit about 'alias char-major'.

I would seriously consider checking your kernel
configuration in 'make menuconfig' if you still have
the .config used to compile the kernel.

I bet your kernel is compiled with a lot of other extra
baggage as well.

OK... working my way through 'make menuconfig' does lead me to the following line:

Sith_Happens · Posted: Wed Mar 16, 2005 7:23 pm Post subject:

Just get rid of all watchdog support, that should fix your problem. Not just i8xx_tco but the top option to enable watchdog timing support in the first place. I thought I mentioned the name of the module in my original post ( i8xx_tco ).

Yeah, Sith is right. I don't have ANY Watchdog Timer support
compiled in either.

Just say N to Watchdog Timer Support and the rest of the options
disappear.

I've seen a lot of kernel configs where every single thing in there
is compiled as a module.

Now is a good time to clean all that stuff out. Check the sound stuff
too. You might have every single ALSA and OSS sound card driver
being compiled every time you rebuild a kernel.

All right... as Sith has suggested

Sith_Happens · Posted: Wed Mar 16, 2005 11:14 pm Post subject:

I hope the only additional action you need to take is to compile and install the kernel. Since you don't have the chipset that the module is meant to take advantage of, you have no need of that support, and the module can't very well complain if it doesn't exist.

One more fork in the road... compiling the kernel... How can I tell if it's sparc32 or sparc64??

Thanks...

Chandra

hmmmmm...... What petinent info frrom this?

Sith_Happens · Posted: Thu Mar 17, 2005 12:39 am Post subject:

Sparc32 and Sparc64 are architectures seperate from x86, sparc is Scalable Processor ARChitecture. If you have a pentium, than it's neither sparc32 or sparc64. :wink:

Well, I must be on the right track... I am no longer faced with:

Did you forget to put CONFIG_810 back in?

Chandra · Posted: Thu Mar 17, 2005 5:18 am Post subject:

Guuess I may have... how do I put CONFIG_810 back in?

Thanks...

egberts · Posted: Thu Mar 17, 2005 5:48 am Post subject:

Actually, it is CONFIG_CND_INTEL8X0. (now that I actually looked at my /usr/src/linux/.config file.

Chandra · Posted: Thu Mar 17, 2005 11:56 am Post subject:

My linux/.config file has the following entries regarding 810:

egberts · Posted: Thu Mar 17, 2005 12:16 pm Post subject:

The issue on hand is missing Intel Audio 810, not the 9 other Intel 810s stuff.

Check for this in /usr/src/linux/.config

CONFIG_SND_I8X0=m

To make things easier, make it a "y"

# cd /usr/src/linux
# make && make modules_install && make install
