I installed the Beta refresh over the Nevada b105. Then, I got the following
panic at the boot (no crash dump was collected; the following is from kmdb
output):
---------------------------------------------------------------------------

I think the panic is occurring around the following line in
audiohd_build_output_amp():
pin = (audiohd_pin_t *)wpin->priv;
I'm using ASUS P5N7A-VM motherboard that deploys nVidia 9300/nForce 730i
chipset and Realtek ALC1200 8-Channel High-Definition audio codec.
(http://usa.asus.com/products.aspx?modelmenu=2&model=2579&l1=3&l2=11&l3=812&l4=0)
With the previous beta, I had experienced the same panic.
Thanks,
