Re: Kernel panic ............a big pain

For what I've read in your previous posting, seems that ext3 driver is a module in your current kernel configuration and you haven't loaded it into the ramdisk (the "2.4.20-8.8aug2003.img" file).

For you to succeed in booting your new kernel, you must either

1) add the ext3 driver to your ramdisk. You can assure that it will be going to your ramdisk with "mkinitrd -f -v \
--with=ext3 /boot/2.4.20-8.8aug2003.img 2.4.20-8.8aug2003.img". If you need modules for your disk subsystem you must add them BEFORE ext3, since the modules inserted by
--with parameters are loaded in the EXACT order you specify in the command line.

2) recompile your kernel making ext3 built-in into the kernel. For this, you should set the "ext3 file system support" to "Y" instead of "M".

Re: Kernel panic ............a big pain

Thanks Mr. Paulo Fessel, for your kind response,

I did select the ext3 in the "File systems" menu in menuconfig command.

And when I recompiled the kernel using the
"nohup make bzImage & " command.
Then I could not find the bzImage in the relevant directory [/usr/src/linux/arch/i386/boot), whereas during the first attempt of kernel recompilation, the bzImage was there.
Here are some error messages as well in the nohup.out file. I request you to review these errors N let me know that how I shuld proceed now.

I did use the find command to locate the bzImage file, but the result was in NO.

Waiting for the same quick response.

Thanks in advance.

Re: Kernel panic ............a big pain

1) I suggest to re-check if you really need kernel recompilation - RH doesn't support recompileted kernels


2) if you going to recompile you kernel, I recommend you to take one of config files from "src/configs" directory and recompile your new kernel according to RH manual

Re: Kernel panic ............a big pain

Hello my dear,

Your kernel panic message indicated that you had a wrong file affectation in your boot process, or that your recompiled kernel didn't support your hardware.

Looking at your compilation error message, it's clear now that there is a hardware support problem (pci).

The trouble is that when you run make xconfig (or menuconfig), each option to choose is to check very carefully, as it influences all the kernel reaction thenafter, and the other devices reaction.

Would you mind if we would start back from the beginning ? Did your first kernel work (the 2.4.20-8) ? What would you like to change in your kernel ?

Re: Kernel panic ............a big pain

Compilation issues are commonplace when you make bzImage a number of times.

The best things you can do are:

1) save your configuration file on a safe place, copying /usr/src/linux-2.4.20-8/.config to another file. I suggest you to use "/root/config" as it will be kept REALLY safe.

2) issue a "make mrproper" to clean things up.

3) copy back your config file to /usr/src/linux-2.4.20-8/.config and issue "make oldconfig ; make dep ; make bzImage ; make modules ; make modules_install".

This should clean the mess up. The powers of "make mrproper" are close to infinity; I was wrestling with IEEE488 software that didn't compile until I issued it. ;-)
