Zeeb <bz@FreeBSD.org> CommitDate: 2026-06-14 22:31:39 +0000 callout: ddb: resolve symbol of callout function In the ddb show callout function try to resolve the symbol of the callout function to improve debugging. In my case I went through various callouts from show ktr to check what they were and this saved me opening lldb/gdb next to it (and still having the old kernel as the panic to debug was upon reboot).
