Please let me know if I can help tracking down the problem. In case you need a score toochain, you can find the one I use at http://server.roeck-us.net/toolchains/score.tgz. Thanks, GuenterIt's not supposed to have any real effect unless the option is selected, but there are a few changes to linker script which must be causing it. 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.*) \
This is the culprit. After removing " .text.*" it builds fine. Guenter
