Try reproduce the panic, and when it drops to ddb, do "show alllocks".

I have few suggestions here, just for you to try it out:

1) Compile all sound modules and related into your kernel as
   part of kernel config instead using it as modules.

2) Try disabling all debuging options, especially WITNESSS, and other
   lock debugging options. Make it as debug-options free as possible.

3) Get http://people.freebsd.org/~ariff/test/es137x_mtx_grumpy.c and  
   replace your sys/dev/sound/pci/es137x.c. Look for "IMPOSSIBLE!"  
   kernel message during loading and startup.

There is a person, reporting quite simmilar panic issue like this. My
initial findings seems pointing to other places, not sound.
