Doing a 'make rpm' with any linux-2.6 (or probably, even linux-2.4 kernel) will fail with the current RH/Fedora RPM macros.
The failure message is this:
Processing files: kernel-debuginfo-2.6.3rc1mm1-12
error: Could not open %files file /usr/src/redhat/BUILD/kernel-2.6.3rc1mm1/debugfiles.list: No such file or directory
RPM build errors:
Could not open %files file /usr/src/redhat/BUILD/kernel-2.6.3rc1mm1/debugfiles.list: No such file or directory
make: *** [rpm] Error 1
The fix is this patch:
