https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289904 Bug ID: 289904 Summary: virtual_oss - panicking after transitioning to the base Product: Base System Version: 16.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: zarychtam@plan-b.pwste.edu.pl I have been using audio/virtual_oss for 5 years without issues. Now, when it's available in base, I just removed the port and left the settings in rc.conf as they were: virtual_oss_enable="YES" virtual_oss_dsp="-S -i 8 -C 12 -c 6 -r 48000 -b 32 -s 512 -O /dev/dsp2 -R /dev/dsp4 -c 2 -d dsp -c 12 -d vdsp -t vdsp.ctl" After reboot, I had a nice panic, so I disabled the service and rebooted again, then started virtual_oss and collected a dump (see backtrace below).
