When compiling sys-kernel/gentoo-sources-2.6.28-gentoo-r5 I get WARNING: modpost: Found 1 section mismatch(es). To see full details build your kernel with: 'make CONFIG_DEBUG_SECTION_MISMATCH=y' Afer compiling with make CONFIG_DEBUG_SECTION_MISMATCH=y I get the following: CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 CC kernel/bounds.s GEN include/linux/bounds.h CC arch/x86/kernel/asm-offsets.s GEN include/asm/asm-offsets.h CALL scripts/checksyscalls.sh CC scripts/mod/empty.o MKELF scripts/mod/elfconfig.h HOSTCC scripts/mod/file2alias.o HOSTCC scripts/mod/modpost.o HOSTCC scripts/mod/sumversion.o HOSTLD scripts/mod/modpost CC init/main.o CHK include/linux/compile.h CC init/version.o CC init/do_mounts.o CC init/do_mounts_md.o LD init/mounts.o WARNING: init/mounts.o(.text+0x26c): Section mismatch in reference from the function autodetect_raid() to the variable .init.data:raid_autopart The function autodetect_raid() references the variable __initdata raid_autopart. This is often because autodetect_raid lacks a __initdata annotation or the annotation of raid_autopart is wrong. CC init/noinitramfs.o CC init/calibrate.o LD init/built-in.o WARNING: init/built-in.o(.text+0x50c): Section mismatch in reference from the function autodetect_raid() to the variable .init.data:raid_autopart The function autodetect_raid() references the variable __initdata raid_autopart. This is often because autodetect_raid lacks a __initdata annotation or the annotation of raid_autopart is wrong. (no more errors) Reproducible: Always Steps to Reproduce: 1. cd /usr/src/linux-2.6.28-gentoo-r5 2. make 3. Actual Results: The same as those in description. Expected Results: No section mismatch.

Do you get a compiled kernel or does this error cause the compile to stop? If you have any additional build logs you can include please do so to assist the maintainers
Section matches are generally harmless and are in many kernel versions and seem to come and go. Please feel free to take these upstream at http://bugzilla.kernel.org.
