BUG_ON(inode->i_state & I_CLEAR);

Disassembly of your code might show which register has i_state ... I wonder if this could possibly be corruption of some sort?  It'd be nice to know what was found in i_state.   Modifying iput() to print it out prior to the bug_on might also help.  Just a thought.

You seem uniquely able to hit it, and you do have a truckload of interesting modules loaded.  :)
