recompile kernel
Hello everybody
I have a little problem (as every one does). I need write support for QNX4FS. I found a Kernel Patch for this on http://qnxfs.narod.ru/ . I've installed Knoppix (c't 3.4 version) on the hdd.
I've tried the http://www.knoppix.net/forum/viewtopic.php?t=3029 , but it didn't work to compile and so on. I got a lot of problems with this. It gives me errors for making "make xconfig" or once later in "make-kpkg --initrd --revision=custom.1.0 kernel_image modules". Then i've tried to download a kernel from kernel.org (2.4.25) and install this one. but this finally didn't work. i changed lilo and made up everything i think and i got a "unable to mount root fs" error.
I forgot to mention, that i always use the old config from /boot/config-.....
Maybe can someone tell me short how i have to recompile a kernel with the old config?
thx a lot.
greetings

That sounds like the initrd did not get made or not made properly (most likely the module you are compiling for now not included in the config somewhere if it is your root file system can't be of much help here never use initrd) for the new kernel, you either have to track down the error or compile with the module included in the kernel (selected yes instead of module) a couple of guides below. BTW it would be modules_image in the kernel compile command line and that would only be needed if you were compiling additional modules (not kernel modules) that you have extracted to the /usr/src/modules directory this option is not necessary if you are only compiling a kernel itself all its modules selected will be built with the kernel_image switch and installed when you install the kernel image package.

Thx for your help
Now i started over with knoppix 3.3 and tried the following:
wget http://developer.linuxtag.net/knoppi...Custom_all.deb
dpkg -i kernel-source-2.4.24-xfs_10.00.Custom_all.deb
cd /usr/src
tar xvfj kernel-source-2.4.24-xfs
cd kernel-source-2.4.24-xfs
cp /boot/config-2.4.22-xfs .config
make xconfig
// here i didn't change anything (jzust looking) and saved the config
make-kpkg clean
make-kpkg clean --initrd --revision=custom.1.0 kernel_image
cd ..
dpkg -i kernel-image<tab> // there is only one (the new one)
// answered the question with inittab with no to continue
then this went without problems
i added a new image to lilo:
image=/boot/vmlinuz-2.4.24-xfs
label=Linux2.4.24
initrd=/boot/initrd.img-2.4.24-xfs
read-only
then i run "lilo" with no errors
when i boot this kernel:
Kernel Panic: VFS: Unable to mount root fs on 03:03
anyone knows why this happens?
thx for your help.
greetings
