kongit Posted April 12, 2004 Share Posted April 12, 2004 I got a kernel panic :oops: :DCouldnt mount the hard drive or something, which i imagine is pretty serious :p Im sure it just needs a little bit more care and adaptation from me, and i'll try later, but if anyone has any tips that would be appreciated. Oh, by the way, im using SuSE and have been told that i shouldnt of just compiled 2.6.0 randomly and needed a SuSE-adapted kernel. How correct is this? Sounds a load of rubbish to me The distro-specific kernels often have patches applied to them that the distro maker thinks need to be there. However it is entirely possible to get a non-distro kernel to load correctly. However jumping from a 2.4 kernel to a 2.6 kernel in many distros involves more than just upgrading the kernel. So far the only distro that I have had near complete success with doing that is slackware. A major cause of kernel panics is an improperly configured kernel and not the kernel itself. You should be able to get a 2.6 kernel to load on almost any 2.4 based distro and get it to load, however somethings might not work correctly. I don't know the specifics on suse on how to get a 2.6 kernel to work with it, however I am positive that somewhere there is documentation on how to do it.

turbomonkeycock Posted April 12, 2004 Share Posted April 12, 2004 My totally uneducated and unfounded conclusion is that it is to do with my boot loader settings. I basically ripped the current one and changed it where i saw fit but I did it in an excited and hurried state, i'll try and boot up back into 2.4 and see if i can fix it Good tutorial btw (Y) I had never made it this far before!

kemical Posted April 12, 2004 Share Posted April 12, 2004 make install will not update lilo or grub automatically. lilo you need to run /sbin/lilo to recycle the config once you have added the proper values in the lilo.conf file, grub, i dunno just add the correct values in the grub.conf file and youll have to restart anyways for th ekernel upgrade it will show up in the grub menu then. lilo on the other hand is different.

kongit Posted April 12, 2004 Share Posted April 12, 2004 make install will install the kernel for fedora. And it adds an extra entry. It will also install for suse, however an extra entry isn't added to grub and it overwrites the last entry. In fact make install is the best way to install it in gentoo. However this won't work on every distro off the bat for grub, but it can be configured to (I don't know how). I haven't had any success with make install and lilo.

kemical Posted April 12, 2004 Share Posted April 12, 2004 when i followed the gentoo instructions i just ran make modules_install then added the entries manually guess this is sort of the same thing but i think i would prefer this way over make install Link to comment https://www.neowin.net/forum/topic/149758-a-guide-to-recompiling-the-kernel/page/2/#findComment-1962387 Share on other sites More sharing options...
kongit Posted April 12, 2004 Share Posted April 12, 2004 gentoo you can't do make install without a little bit of effort. It really isn't worth it for gentoo, however with fedora it makes an initrd and appends it to the grub automatically. I believe that in order for fedora to properly function it needs this, and it is far easier just to let the make install make and install it.

turbomonkeycock Posted April 16, 2004 Share Posted April 16, 2004 I think I enabled support for all file systems! Is this bad? Is there a way that I can find out what FS I am using? And also how do i find the hard drive that it should load from? I believe that its hda6 on my computer but thats a bit weird as i have one hard drive :s Link to comment https://www.neowin.net/forum/topic/149758-a-guide-to-recompiling-the-kernel/page/2/#findComment-1978297 Share on other sites More sharing options...
kongit Posted April 16, 2004 Share Posted April 16, 2004 Adding support for all filesystems should not mess anything up, however it will affect the kernel size and might affect performance. If your linux is working you can check your fs in /etc/fstab. hda6 is the 6th partition on the 1st drive.

vuerro Posted August 15, 2004 Share Posted August 15, 2004 after doing; make bzImage && make install modules modules_install i didn't get the results I needed - probably because I needed to move some files from the usr/src directory (maybe an addition for the how-to?) so I did the following -> make rpm and it did (after taking a hour) and places it in /usr/src/redhat/RPMS/i386/ (and a src.rpm in /usr/src/redhat/SRPMS/) so I was able to rpm the kernel (rpm -ihv kernel-..) and I found a vmlinux matching the kernel version in /boot and after that I needed to make a custom initrd using /sbin/initrd -something- (on a winbox now.. :rolleyes: ) because I have a RAID controller card installed.. manually edited the /boot/grub/grub.conf file (copied previous linux startup line's and adjusted accordingly) et voila :happy: new kernel up and running it takes a bit longer but it worked twice for me..

mFC_ Posted October 27, 2004 Share Posted October 27, 2004 it would be good if someone went over make menuconfig since lots of people are having problems with kernel panics and such. also, is there any way you can find .config files that are ready to go without make menuconfig? i'm sure that would make life a little bit easier for some.

3nd3r Posted November 7, 2004 Share Posted November 7, 2004 after the kernel is put in /usr/src/ i make a symlink from the new kernel dir to linux. then i copy my old .config to the new directory. I then run a make menuconfig to check over the options I then mount my /boot partition. I then run this command: make; make modules modules_install install I also run gentoo and grub as my bootloader as i find it is more robust than lilo. btw, i have an old .config here: http://3nd3r.info/.config Link to comment https://www.neowin.net/forum/topic/149758-a-guide-to-recompiling-the-kernel/page/2/#findComment-584880912 Share on other sites More sharing options...
kairon Posted December 3, 2004 Share Posted December 3, 2004 Is it possible to save the current configuration of my precompiled kernel that came with Mepis and works beautifully with my hardware, and be able to use it with a newer self-compiled kernel? That way I can take out what I know for sure I don't need and yet still maintain a fully functional kernel that supports my needs.I have compiled from scratch with Gentoo before, but I really would rather not get into that again since it can be frustrating Link to comment https://www.neowin.net/forum/topic/149758-a-guide-to-recompiling-the-kernel/page/2/#findComment-585035326 Share on other sites More sharing options...
mr_demilord Posted May 5, 2005 Share Posted May 5, 2005 You can better use the kernel of your distro, every version of the kernel has other compiling option RTFM, you cannot compile a 2.6 kernel with 2.4 kernel options without screwing things up.

mr_demilord Posted October 8, 2005 Share Posted October 8, 2005 tar -xzvf linux-2.6.0.tar.gzcd linux-2.6.0 make menuconfig After your machine takes a bit of time to compose the menus, you should see the Linux kernel menu system. The menu gives you the ability to choose which options are included in your kernel. After choosing these options, you'll be able to compile your kernel. Compiling the kernel First, type in the following. make bzImage If you use LILO as your boot manager, then type the following. make install If you configured your kernel to use modules, which many people want to do, you'll need to type in the following command. make modules make modules_install This wont work, the proper way is to check your current .conf file of your distro, most distros uses specific options, like the initrd ramdisk size, SuSE uses automount for example. The proper way is to always use make clean && make mrproper Never asume that the kernel is clean after a download! Check if you use make menuconfig that it doesn't load your current .conf file, move it if necessary, otherwise you get all kinds of depraced warnings. A distro kernel is a modified kernel with other options the vanilla kernel hasn't. if you are ready and modified the kernel do make bzImage make modules make modules_install Then do make install. Check the grub.conf Remove the symlinks in the /boot dir and create new ones and point them to the old kernel. reboot Link to comment https://www.neowin.net/forum/topic/149758-a-guide-to-recompiling-the-kernel/page/2/#findComment-586642217 Share on other sites More sharing options...
