Hi,

Compilation of 2.5.52bk6 fails due to the following error :

ld -m elf_i386 -e stext -T arch/i386/vmlinux.lds.s arch/i386/kernel/head.o

drivers/built-in.o: In function `via_kt400_enable':
drivers/built-in.o(.init.text+0x4e4f): undefined reference to

Concerning config options:

CONFIG_AGP=y
# CONFIG_AGP3 is not set
CONFIG_AGP_VIA=y

Best regards,
