Subject:   PCM broken in 4.7RC

When compiled in or kldloaded PCM hangs the machine (either during boot,
or when loaded).

When booting no error message is displayed, when kldloaded the it tries
to attach and comes back with...

device_probe_and_attach: pcm0 attatch returned 6

the machine then hangs.

the following is a kernel without pcm's dmesg output.

latest release of 4.7RC, 2 weeks ago all was well and good.

The machine is a Toshiba portege 4000 running 4.7RC as of 2 hours ago.
