Error during "make bzImage"

RedHat 9 is installed on a multiprocessor machine. The kernel version is 2.4.20-30.9smp. For debugging purpose I have to compile this kernel. I performed the following steps:
- Downloaded kernel-source-2.4.20-30.9.i386.rpm and installed them.
- Instead of "make config" I copied the configuration file /boot/config-2.4.20-30.9smp to /usr/src/linux-2.4.20-30.9/.config
- make dep
It gave the following error "md5sum: WARNING: 1 of 13 computed checksums did NOT match" but the exit code was 0.
- make clean
- make bzImage
This was unsuccesfull with exit code 2. There were large number of errors and warnings. Some of the errors are as follows:
-------------------------------------------------------------------------

Can anyone guide on this? I also did "make checkconfig" which gave many such lines:
arch/alpha/kernel/irq_smp.c: 127: need CONFIG_DEBUG_SPINLOCK.
arch/alpha/kernel/osf_sys.c: 1388: need CONFIG_OSF4_COMPAT.
arch/alpha/kernel/semaphore.c: 60: need CONFIG_DEBUG_SEMAPHORE.
arch/alpha/kernel/smp.c: 1050: need CONFIG_DEBUG_SPINLOCK.
arch/alpha/kernel/smp.c: 1142: need CONFIG_DEBUG_RWLOCK.

Thanks,

why dont u try to 'make menuconfig' for change.. rather than using an existing config file.. maybe some config options are causing a problem. Also i read somewhere that developers of distros often add some features to the existing kernel to enhance performance.. so couldnt hurt to do the config over again.

Thanks for your help. I succesfully compiled the kernel and even rebooted into it. My mistake was I had not done make oldconfig.

Now I have another problem. I installed a wrong patch for kdb (kdb-v4.4-2.6.6, instead of kdb-v4.3-2.4.20). The patch did not install properly there were .rej files. But I still compiled the kernel succesfully. Now since kdb did not work I reinstalled the kernel source (even deleted directory linux-2.4.20-30.9 in /usr/src). But now the "make modules" exits with errors like below:

As far as I know (from strace patch -p1 kdb.....)the kdb patch has only modified file in the linux source tree which I have installed fresh now. I have no idea why the same steps of compilation taht passed before are failing now. Is there any way that I can restore the initial state?

thanks,
