How about other patches from http://staff.mybsd.org.my/skywizard/FreeBSD/sound/ especially sound.c.diff / mixer.c.diff. It fix serious refcount miscalculation, causing kernel panic while unloading busy sound driver *twice*. I think it's for *everybody*, including vchan.c.diff. -- Ariff Abdullah MyBSD http://www.MyBSD.org.my (IPv6/IPv4) http://staff.MyBSD.org.my (IPv6/IPv4) http://tomoyo.MyBSD.org.my (IPv6/IPv4)
