Let hw.snd.maxautovchans=3D0 , and set hw.snd.pcm0.vchans=3Dmorethan_1. It's probably not because of via driver, or the driver itself triggering somewhere else. If you can, try to trigger the panic during single user mode. It's much verbose there. Other people reported better result with those patches, so I hope we can refine your current situation. How about your vmstat -i? How about enabling dxs back (hint.pcm.0.via_dxs_disabled=3D"0") ? -- Ariff Abdullah MyBSD http://www.MyBSD.org.my (IPv6/IPv4) http://staff.MyBSD.org.my (IPv6/IPv4) http://tomoyo.MyBSD.org.my (IPv6/IPv4)
