Actually, for parisc, its not reasonable. It's expected that our modules have multiple text sections (we have to use -ffunction-sections to generate them in order that the PCREL17 jump stubs can be interleaved). The problem looks to be that some linker error gave the one of the named function text sections a duplicate name. Helge, can you post he objdump info that shows which section had a duplicate name? Even with the duplicate name, though, the module should be perfectly loadable. James
