To: freebsd-stable@freebsd.org MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Hello, it looks like there is a bug in kldunload that can easily crash the whole OS. It's easy to reproduce it: 1. kldload snd -- loads all sound drivers and probes hardware; 2. kldunload snd -- boom, kernel panics. Modules cannot be unloaded separately. Of course that's stupid to kldload all of them together, but that shouldn't crash OS on unload, right? I have no sound related stuff in my kernel, and of course I didn't load any _snd.ko modules prior to kldload snd.
