That's the reason - in GENERIC kernel config, there are lines options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores so no need to load any kld for SysV support. Also, the same is valid for my 13-STABLE kernel config file, but not for my 14-STABLE one. > > Maybe kernel config differences matter, no idea. > > > > Anyway, any idea how to proceed?

For now, I found simple workaround - in addition to sysvshm kld, I need both sysvmsg and sysvsem kld modules, then ipcs works. Also, number of kern.ipc oids is now 55. I need ipcs just for diagnose and development, for normal run it is not necessary, anyhow, if a need will be, it is easy to load necessary modules. Thanks for hints, discusion is really useful, solution found. More, I understand the reason now. It was no regression actually, just kind of pilot error. Regards, Milan
