Hint needed: howto compile same kernel version

["M. Hotze" <m.hotze@wanadoo.nl>]

Hi,

I would like to make a small delta between running stable version 2.4.27-9 of the kernel and my 'to be compiled' kernel. 

Don't know how to do it, as available kernel is 2.4.27-10. This is what I tried:
-Downloaded kernel-source-2.4.27-10-10sarge1 and kernel-headers-2.4.27-2-sparc64
-Made a link from ../include from kernel-source to the kernel-headers
-Used /boot/config-2.4.27-2-sparc64
-Compiled (oops, first pass forgot the --initrd), but my kernel has much different size than original one

I also tried auto-apt run apt-get -b source kernel-image-2.4.27-sparc=2.4.27-9, but did not succeed.
Build command 'cd kernel-image-2.4.27-sparc-2.4.27 && dpkg-buildpackage -b -uc' failed.
E: Child process failed

How is the stable kernel 9sarge1 for sparc64 actually compiled? Can anyone give me a hint?

Thx,
Maarten
