[NOTE: added linux-audit to the CC line, I should have done that earlier]

I believe I can reproduce this now; I'm seeing slightly different panics, but 
it is "close enough" and based on some quality time with the code I believe 
they are both symptoms of the same root cause.

To help verify that I'm heading down the right path, could you share your 
audit configuration as well?  If that's not possible, can you at least confirm 
that you using a few audit directory watches?
