https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195458 Konstantin Belousov <kib@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kib@FreeBSD.org --- Comment #53 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Glen Barber from comment #52) It is physically impossible to hang on a line which is not loop. I suspect that it is either the buffer flush code, or softdep worker thread which loop and cause shutdown thread to wait. It is good that you have reproducable case and willing to move it further, previous reporters only bother to whine. See https://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-deadlocks.html for the instructions on how to configure your kernel and what information to get. -- You are receiving this mail because: You are the assignee for the bug.
