>Description:
Hi,

I tried to install OSS on my system. It results in a kernel panic if I add `oss_enable="YES"` to my rc.conf. However if I try to load it with kldload, my system freeze irremediably. I tried to recompile my kernel with intern sound drivers disabled, unsuccessfully. I tested it on FreeBSD 8.2 RELEASE and all worked.

Here the backtrace of the panic :

<118>Starting slim.
<118>Starting Open Sound System
panic: make_dev_credv: bad si_name (error=17, si_name=sndstat)
cpuid = 1
KDB: enter: panic
panic: from debugger
cpuid = 1
KDB: stack backtrace:

Installing Open Sound System on FreeBSD 9.0-BETA2 amd64
1. with `oss_enable="YES"` in rc.conf
2. by `kldload osscore`
