devfs kernel panic

From: Richard Cox <conardcox_at_earthlink.net>

I was trying to get xine going on 5.2 Current and ran into a kernel panic.  
After a bit of investigating, I discovered I could reproduce the panic 
consistently just by trying to stat /dev/dsp1 (i.e., just an 'ls /dev/dsp1' 
will cause the kernel to panic).  Here are the particulars, please let me 
know if there is any more information you would need to track this down:

rocket:/usr/src/sys/fs/devfs]# kldstat
