loading modules with an Initrd image?


Several times i recompiled the 2.6.13 kernel but all of them i get some errors but not all time I mean i recompiled the kernel then system booted normally but in the second boot it gives lots of errors(generaly after hotplug started) and other boots some of them normal but some not I tried to use my laptop with that kernel but some times it makes me crazy (i used def config file of slack 2.6.13 kernel and made some changes like acpi and cpufreq opts)
-I have to use 2.6 kernel becouse of my i pro wireless hardware
-I wanna use may laptop so much time with battery so the kernel have to have cpufreq scalling options and i know that the def 2.6.13 kernel package have them as modules

Now the question is can i load acpi modules and cpufreq scalling modules with an initrd image if yes how?
I googled about initrd but all topics are about loading sata modules or reiserfs module is initrd only for sata or raiserfs?

Hi,
initrd is generally used when you don't have essential system components compiled in as kernel modules. Root filesystem (as a module) comes to mind immediately. I've never made initrd with slackware and i've never had a problem before. Essentially I compile root filesystem in the kernel...also i've always compiled cpufreq and acpi as modules. Try making a kernel for your system taking the default 2.6.13 kernel config file as a starting point. Compile the filesystem (reiser or ext3 whatever you are using). Once you successfully compiled you own kernel...you have the .config file which can be used over and over again.

As I said, i've never used initrd so I wouldn't know if one can load acpi and cpufreq via initrd. I always load them via /etc/rc.d/rc.modules script. I add those entries at the very end of the file and it always works for me.

Thank you I added the lines in to modules script and acpi and cpufreq options work fine for me too

I use the default kernel 2.6.13 out of Slackware-current and load the ACPI modules with an initrd.gz without problems. If I add the modules to /etc/rc.d/rc.modules fan and battery are not working. With "mkinitrd -c -k 2.6.13 -m ac:battery:fan:processor:thermal:video:exportfs:xfs" I create an intrd.gz which loads my needed ACPI and xfs modules so that there is no problem to boot my filesystem and a perfect working ACPI.

Fluxx.

I'm using def 2.6.13 kernel too.
I added the lines to modules script and everything is good now
But I thing i will try making an initrd and i will get acpi work via initrd
