I have installed Debian Testing via the netinstall, and have a kernel
2.6.12-1-386 from Debian testing (etch). I'd like to make some changes
to the kernel source, namely the device driver for my sound chip. I
installed what I thought was the kernel source, and expected to see
"-1-386" in the source tree top-level Makefile's symbol for
"EXTRAVERSION". However, it's blank.
I built this kernel, booted from it, and had different behavior from the
one that came in binary form with the netinstall. The problem is with my
CD-DVD RW. With the default kernel, it appears fine as /dev/hda and
works with several apps. With my compiled kernel, it appears as
/dev/scd0 and doesn't work with several apps.
How can I get the actual kernel source used to build the binary kernel
installed with Debian netinstall? I expect the procedure to be this:
1. apt-get install kernel-source-something
2. cd /usr/src/kernel-source-something # verify Makefile has
EXTRAVERSION = -1-386, change to -1-386-custom
3. cp /boot/config-2.6.12-1-386 .config
4. make xconfig # just save and quit
5. make bzImage modules modules_install # verify
/lib/modules/2.6.12-1-386-custom
6. cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.12-1-386-custom
7. cp System.map /boot/System.map-2.6.12-1-386-custom
8. mkinitrd -o initrd.img 2.6.12-1-386-custom && cp initrd.img
/boot/initrd.img-2.6.12-1-386-custom
9. Edit /boot/grub/menu.lst, clone entry for default kernel
As I said, doing this I didn't see the telltale EXTRAVERSION = -1-386,
and when finished the kernel wasn't the same as far as /dev/hda
behaviour and some other things scrolling by on the boot console.
