Hi, my apologies for not having a lot of time to look at this.  I've been at the Linux Plumber's Conference and Kernel Summit this whole week.

What did you have running which triggered this, and can you try the patch that I sent in this patch, and see if you get the same other BUG_ON?   And if you have the stack trace easily to hand, it would be useful to make sure that part is the same as well.

Many thanks,
