https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200384 Bug ID: 200384 Summary: ctld Product: Base System Version: 10.1-STABLE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: olgeni@FreeBSD.org Created attachment 157032 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=157032&action=edit Sample ctl.conf Loading ctld causes a panic at boot (ctld_enable="YES" in rc.conf) when the following kernel options are enabled: DEADLKRES, DEBUG_LOCKS, DEBUG_VFS_LOCKS, DIAGNOSTIC, INVARIANTS, INVARIANT_SUPPORT, WITNESS. It seems repeatable so far - the options were actually enbled to track down a possible deadlock elsewhere.
