Hi, I haven't seen a Kernel Panic like this for a long time... i.e. repeatable and due to a single command. I have compiled the port /usr/ports/audio/oss and installed it on FreeBSD11. A ran /usr/local/sbin/ossdetect which created the file /usr/local/lib/oss/etc/installed_drivers. Contents: Code:oss_hdaudio #Intel High Definition Audio (CPT) When i run /usr/local/sbin/soundon The system panics.. Code:osscore.ac97_amplifier="0" panic: Lock (sx) module subsystem lock sx lock not locked 0 /usr/src/sys/kern/kern_module.c:219 cpu_id = 1 : audio/oss Build 4.2-build2011 Any ideas? I have taken out any reference to sound in a custom kernel # Sound support #device sound # Generic sound driver (required) #device snd_cmi # CMedia CMI8338/CMI8738 #device snd_csa # Crystal Semiconductor CS461x/428x #device snd_emu10kx # Creative SoundBlaster Live! and Audigy #device snd_es137x # Ensoniq AudioPCI ES137x #device snd_hda # Intel High Definition Audio #device snd_ich # Intel, NVidia and other ICH AC'97 Audio #device snd_via8233 # VIA VT8233x Audio # make buildkernel KERNCONF=GENERIC # make installkernel KERNCONF=GENERIC Thanks GQReceived on Wed Feb 10 2016 - 08:51:09 UTC
