Anything shown on the actual console?  There's some error conditions
which emit messages via syslog() only (see lines ~278-286 of
src/sbin/savecore/savecore.c).

Also, any chance of output from savecore -f -vv?  There's some extra
debugging info which might come in handy (lines ~288 of
src/sbin/savecore/savecore.c).
