https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270709 Bug ID: 270709 Summary: audio/oss Kernel panic at every shutdown after installing OSS Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: crees@FreeBSD.org Reporter: martenvdberg@hotmail.com Assignee: crees@FreeBSD.org Flags: maintainer-feedback?(crees@FreeBSD.org) Created attachment 241357 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D241357&action= =3Dedit coredump After installing the oss package, a kernel panic occurs every time the comp= uter is shut down.=20 Steps to reproduce: - Fresh install of FreeBSD 13.1-RELEASE. Tested this with bot UFS and ZFS filesystems which does not make a difference. - Build and install a custom Kernel with all sound support removed as instructed by the audio/oss port. - Install the oss package - set oss_enable=3D"YES" in /etc/rc.conf - Reboot - Then the kernel panic occurs after the shutdown command is give (core dump attached) - The kernel panic can also be provoked by first shutting down oss (# servi= ce oss stop) and then shutting down mixer(8) (#service mixer stop) The sound card (ASUS Xonar D2X) does work with the oss drivers. dmesg() not= es that the Open Sound System is started. Only other message related with this issue is "pci0:6:4:0: Device leaked IRQ resources". Hardware in my setup: Motherboard: Asus Z9PA-D8 motherboard CPU:2x Intel Xeon E5-2697 v2 @ 2.70GHz GPU: NVIDIA GeForce GTX 1080 ASUS Xonar D2X Workaround: Because the panic occurs whenever mixer(8) is shut down after oss is shut d= own, the following workaround will prevent the panic from occurring: add "# REQU= IRE: oss" to /etc/rc.d/mixer, which ensures mixer(8) shuts down before oss.
