https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200319 --- Comment #16 from Kristof Provost <kp@freebsd.org> --- Thanks Oleg, The demo script nvass attached also worked for me to trigger the problem. I've not yet tried your setup, but I'm confident it'll also work. I think I understand the problem in general terms (but I need to look at details for the full story). Basically, carp and bridge deadlock against each other because carp calls into bridge which calls into carp (or vice versa). I believe the patch in D3133 is not correct. (See also ae@'s comment there.) It removes locking protection where it should be present, and this is what seems to fix the problem. This issue is still on my todo list, but I can't promise when I'll get the time to look into it. -- You are receiving this mail because: You are the assignee for the bug.
