While you guys are looking in snd_pcm here is a bug someone pointed out to on the lists in another form that I narrowed down. If you build snd_pcm and your another driver as modules and then only load snd_pcm.ko and not load your more specific driver you can panic the system every time by doing a "sysctl hw.snd.maxautovchans=(something other then current)". This has been sitting in my TODO list for awhile but I know nothing about sound driver code so you'd probably have more luck then I would. :) I'll attach the backtrace I grabbed from my latest CURRENT kernel. (I haven't checked if this is in a PR or not yet.) -- Ryan Sommers ryans_at_gamersimpact.com
