I wondered what that crash was on boot-up.  Sometimes
it does boot though!  Anyway...

I also have almost everything on IRQ9.  I'm not sure
its FreeBSD - I think its the Vaio :(  Just checked
Windows 2000 and it lists USB, video, network,
firewire, audio _ALL_ on IRQ9.

Perhaps your pcm problems come from the interrupt not
being delivered at all - try moving a USB mouse while
your audio is playing.  I have a hacky-hack to make my
vaio's audio play normally.  I noticed that since the
audio and usb share an interrupt, moving a USB mouse
gets the pcm interrupt handler called - which results
in normal sound.

Sorry, I don't have my own web page address handy - I
never go there ;)  I'll send it privately.
