compiling kernel 2.5.70 (experimental-unstable)
Thanks to the kernel compile thread here, i am able to start compiling my kernel ^_^ even tho i am a n00b on linux and installing slackware is kinda hard to learn at the beginning, it really taught me a lot about the linux operating system :) right now as i am posting this i am running all the makes for the compile, and wonders if they are right.

I have grub installed, and my line for grub to boot up slackware is:


kernel (hd0,4)/boot/vmlinuz root=/dev/hda5 devfs=mount hdc=ide-scsi hdd=ide-scsi
as for the Makefile, i read the comment about line 74 to uncomment the line that it exports the vmlinuz into /boot. do i have to adjust my make lines to put the vmlinuz into the grub loader, or just leave it as the lilo method?

what i have is this:

make xconfig
then after selecting the right modules,


make dep && make clean bzImage modules modules_install
is that correct? if you can please gimme a hint :)

modr12 05-31-2003 04:12 PM

first you need new modules-init-tool or you can't load the module
as for the Makefile, i read the comment about line 74 to uncomment the line that it exports the vmlinuz into /boot. do i have to adjust my make lines to put the vmlinuz into the grub loader, or just leave it as the lilo method?
do you want really erase your old kernel ?
if you have somme problem with the new ?
make make bzImage
make modules_install
copy and arch/i386/boot/bzImage to /boot
add an entry to grub

modr12 05-31-2003 04:14 PM

i ve forget
for the new modules-init-tool
./configure --prefix=/usr
make move old <= for keeping the old lsmod ....

kazuni 05-31-2003 10:22 PM

thanks a lot.
you're right, i cannot load the modules correctly. they got :

usb-ohci.o: unreferenced local variable  _mem_copy
or soemthing like that. frustrating.

anyways, yeah i did make a backup copy of my own vmlinuz to vmlinuz.backup and i know how to do the grub-alternative boot so that i can always get back to the original distro.

as for the modules-init-tool what is that? and what is it for?

i did

make dep && make clean bzImage modules modules_install
and it compiled fine... except that when i boot with the new image and the new system map, all the modules screwed up (can't load due to some errors like that i indicated at the beginning) was that caused by that?

to keep the old lsmod as in my list of old modules?

modr12 06-01-2003 10:39 AM

error like QM_MODULES: Function not implemented ?

if yes you need to install modules-init-tools

kazuni 06-01-2003 12:53 PM

hm. never seen that message.

but the funny thing is that i get kernel panic all the time now, lol.
lucky that i backed up all the system map vmlinuz and learned grub before hand or else i'll be in a lot of sh*t. hehe.

anyways, now here's one really simple question,

does every distribution's kernel-source package (either in RPM or in tgz or bz2, whichever) do they include a sample .config or a .config that is exactly the same as their build of the kernel or not? or just one that was generated by menuconfig or xconfig? because i get inconsistency problems for compiling. i've compiled for almost 2 days now and still didn't get the right modules, heh. i am now experimenting using the original .config that was unpacked with the kernel source, and *ONLY* changed the opcode from i386 to K7 (i have an Athlon XP 1800 and an ECS K7S5A motherboard)

oh, and is it safe for me to take off the modules for ISA/Firewire? as i don't really need those but during compile it gives warning saying that those variables are redefined...

modr12 06-01-2003 04:20 PM

yes /boot/config or a thing like that
the new modules must have been install in /lib/modules/2.5.70
when installing the new modules-init-tools
i remember that to you have to generate a conf file
i don't remember the command he is in the install file
first the modules don't have been install aka no /lib/modules/2.5.70 ( go in usr/src/2.5.70 an make modules_install)
or the conf files dont have been make ( see the install file for the command)

kazuni 06-01-2003 06:07 PM

haha i finally run to the problem you described. right now, i got all the things compiled properly, only that it doesn't load the modules correctly (lucky that i rememberd all the names for my usb devices (i.e. mouse)
by default it loaded:


Module                  Size  Used by    Not tainted
input                  3264  0  (autoclean)
pcmcia_core            40032  0
ide-scsi                8784  1

i manually loaded them myself:


Module                  Size  Used by    Not tainted
usb-storage            63540  0  (unused)
soundcore              3652  0  (autoclean)

keybdev                2080  0  (unused)
hid                    19204  0  (unused)
usbmouse                2296  0  (unused)
usb-ohci              18984  0  (unused)
mousedev                4244  0
usbcore                61696  0  [usb-storage usb-uhci hid usbmouse usb-ohci]
input                  3264  0  (autoclean) [keybdev hid usbmouse mousedev]
ide-scsi                8784  1

all seems fine (just that i have to make an auto script to mount and unmount usb drives, install usb mouse, etc... but that's the purpose of fstab, heck :P)

but there's one problem,
when i do


insmod emu10k1
it gave me a load of errors:

errr... i donno what they mean, but heck, the only thing now not working is the stupid sound card (SBLive! value) :P

i am now looking for that modules-init-tool, so here i go hunting :D

oh and thanks a lot for explaining all those settings, much appreciated dude :)

oh and just out of curiosity, i posted my dmesg:

kazuni 06-01-2003 06:09 PM

oh, and i am now messing with kernel 2.4.20 not 2.5.70 :P (too much of a mess in 2.5.70, many c codes for devices are not implemented correctly i.e. unresolved links/symbols... i'll wait for the stable version that comes out later :))

kazuni 06-01-2003 07:41 PM

ah. i found out the error given by the insmod emu10k1

it was because i didn't insmod ac97 sound soundcore and stuff like that...

so now, i got a bashrc script to run the insmod :P but it was kinda annoying as it defeats the fstab purpose (can't mount cd using supermount -_-)

oh yeah, the modules-install-tools was really helpful, i compiled it and installed it and it runs perfeclty fine :)

neo_nirvane 06-02-2003 11:07 AM

ah ha, u are far more lucky. i was facing problems loading the emu10k1 after recompiling my first kernel.... hell, when i typed modprobe emu10k1 it even said can't locate the modules..... i've tried both install it as modules or straight into the kernel...

kazuni 06-02-2003 01:24 PM

lol neo, u sure u turned the option of compiling emu10k1 is there? make sure u also compiled ac97, and ac97_codec, soundcore and sound :)

kernel 2.5.70 after compiling doesnt works - help to make it work
Hey ,

I compiled the kernel 2.5.70 and i got the bzImage. Now when

i try to boot it , it is not booting.

it says

Uncompression Linux kernel...OK.Linux kernel is booting..

and then that's all

nothing goes more than that

can anyone help me
