Hi, I've hit an unpatched kernel issue while trying to build on sources see the header for version details.. arch/i386/kernel/built-in.o(.init.text+0x1585): In function `setup_arch': : undefined reference to `acpi_boot_table_init' make: *** [.tmp_vmlinux1] Error 1 It seems that I would need to install (centos/redhat) patches after installing/building the kernel source tree from the kernel-2.6.9-34.EL.src.rpm Is that correct ?? thanks, Peter
