It's caused by the old (6.x version) kldxref(8) binary trying to hash the *.symbols files that are installed along with debug versions of kernel and module objects, and that contain symbol information needed for debugging, and aren't dynamically linked ELF files. So the old kldxref(8) ignores these files, but issues a warning. Once you upgrade to 7.x, you'll have also installed the new (7.x version) of kldxref(8) that is aware of .symbols files, so warnings will be gone. Technically, kldxref(8) should be a cross-tool (in the buildworld sense), but last time I tried to convert it to be a cross-tool several years ago it wasn't very easy. It's quite possible it will be easier now that we only support limited upgrade paths. Cheers, -- Ruslan Ermilov ru@FreeBSD.org FreeBSD committer
