I am trying to compile pfeifer-2.4.22-r2 sources as a 2.4 fallback if 2.6 does not work, and so I need device-mapper to access my LVM volumes (root, home) However, make bzImage fails at the link step with the following errors: gcc -E -C -P -I/usr/src/linux-2.4.22-pfeifer-r2/include -imacros /usr/src/ linux-2.4.22-pfeifer-r2/include/linux/config.h -imacros /usr/src/ linux-2.4.22-pfeifer-r2/include/asm-i386/segment.h -imacros /usr/src/ linux-2.4.22-pfeifer-r2/include/asm-i386/page_offset.h -Ui386 arch/i386/ vmlinux.lds.S >arch/i386/vmlinux.lds ld -m elf_i386 -T /usr/src/linux-2.4.22-pfeifer-r2/arch/i386/vmlinux.lds -e stext arch/i386/kernel/head.o arch/i386/kernel/init_task.o init/main.o init/ version.o init/do_mounts.o \ --start-group \ arch/i386/kernel/kernel.o arch/i386/mm/mm.o kernel/kernel.o mm/mm.o fs/fs.o ipc/ipc.o \ drivers/acpi/acpi.o drivers/char/char.o drivers/block/block.o drivers/misc/misc.o drivers/net/net.o drivers/char/agp/agp.o drivers/char/drm/ drm.o drivers/ide/idedriver.o drivers/cdrom/driver.o drivers/pci/driver.o drivers/video/video.o drivers/usb/usbdrv.o drivers/media/media.o drivers/md/ mddev.o crypto/crypto.o drivers/sensors/sensor.o \ net/network.o \ grsecurity/grsec.o \ /usr/src/linux-2.4.22-pfeifer-r2/arch/i386/lib/lib.a /usr/src/ linux-2.4.22-pfeifer-r2/lib/lib.a /usr/src/linux-2.4.22-pfeifer-r2/arch/i386/ lib/lib.a \ --end-group \ -o vmlinux drivers/md/mddev.o(.text+0x8cf3): In function `lookup_device': : undefined reference to `path_init' drivers/md/mddev.o(.text+0xfaf4): In function `do_page': : undefined reference to `generic_fls' make: *** [vmlinux] Error 1 Removing device mapper from the kernel configuration fixes the problem.

Created attachment 18158 [details] My .config for the kernel; disabling device mapper allows it to compile
I've now had more chance to investigate; it's a regression since pfeifer-sources-2.4.22-r1, as it compiles there with the same .config
Correction; it doesn't work in r1 or r0; the same error occurs. Brainfart, I'm afraid :(
Can you try gentoo-test-sources (which is what pfeifer-sources has become). File any bugs (even if it's the same thing) as new, so I can track them as gentoo-test-sources.
