There are two changes to vmlinux.lds.h. One is to KEEP a few input sections, that *should* be kept anyway. The other is to bring in additional sections into their correct output section. Could you try reverting those lines of vmlinux.lds.h that change the latter, i.e.: - *(.text.hot .text .text.fixup .text.unlikely) \ + *(.text.hot .text .text.fixup .text.unlikely .text.*) \ - *(.bss) \ + *(.bss .bss.[0-9a-zA-Z_]*) \ etc? Thanks, Nick
